DEAR ABBY: I'm a sophomore at a religious university that is well regarded in both secular and religious circles. I came here to become a doctor because the pre-med program has an outstanding acceptance rate to medical school.

However, in my third quarter I took a religious studies course and fell in love with the department. I'd like to pursue a career in this field, perhaps as a professor. I have an excellent GPA and am working three jobs.

My problem is that my parents are not supportive. They think I'm being impractical and will end up working in a fast-food restaurant for the rest of my life. I thought they'd be thrilled I have taken such an interest in our faith. Becoming a doctor no longer interests me. How can I convince them that I can major in religious studies and not live in poverty? -- REBEL IN CALIFORNIA

DEAR REBEL: You shouldn't pursue a career in medicine unless your heart is in it because if it isn't, you won't make a very good doctor. Unless you plan to take a vow of poverty, a career in religion doesn't mean you'll end up living hand-to-mouth. While money is important, it's more important that you devote your life to something that gives you emotional gratification.

DEAR ABBY: As a divorced dad, I'm hoping you'll address a problem I have encountered in trying to co-parent my children. My daughters are often invited to parties and sleepovers, which sometimes happen during my parenting time, as well as during my ex-wife's parenting time. The invitations to these events, however, are almost always sent to my ex-wife's home or email address.

Aside from the problems that have occurred because the information wasn't forwarded to me in a timely manner, I think it's sexist for invitations to be sent only to the mother. It reinforces the outdated notion that a woman's role is to raise children, and a father can't be an active parent. Would you please remind your readers that the most appropriate way of inviting a child who has two households is to send the invitation to both parents? -- MODERN DAD IN ROSWELL, GA.

DEAR MODERN DAD: I think you have delivered that message very clearly. However, if not every reader takes it to heart, make a point of discussing with your ex-wife what activities may have been scheduled for your daughters while they're with you. That way they won't miss out on anything.

DEAR ABBY: I was recently diagnosed with a cancerous tumor on my tongue that has made it extremely difficult and painful to talk. The problem is I don't know how to handle encounters with strangers in public places -- i.e., grocery stores, libraries, etc. I have always been polite and courteous, but now I can do no more than nod. What would you suggest in this situation? -- SUDDENLY SILENCED IN FLORIDA

DEAR SUDDENLY SILENCED: Make eye contact with the people you would normally greet verbally and give them a smile as you are already doing. If someone tries to engage you in conversation, point to your throat, shake you head "no," and mouth the words "can't talk." If you feel further explanation is necessary, have cards printed that state, "I am unable to speak." That way, no one should take offense.

DEAR ABBY: I have worked in a medical clinic for 35 years and hear a lot of complaints about the wait for doctor appointments. May I explain some of the reasons for it?

Sometimes the doctor arrives late, but other factors can cause delays:

1. If you need to be seen, call first to get an appointment time. Most offices leave open spots to accommodate urgent-care matters. If you just walk in, we must work you in with patients who already have appointments, which pushes the doctor behind.

2. Do NOT come an hour early and announce in front of the entire waiting room that you must be somewhere and expect to get worked in before your scheduled time. Reschedule instead.

3. Always bring your insurance cards with you. Do not tell us to call another doctor's office to get the information.

4. Don't walk in with forms you need filled out and signed by the doctor and expect someone to take care of it immediately. It requires your chart to be pulled, a nurse to fill out the information and the doctor to look over the form and sign. Instead, leave the form. We'll mail it or call you to pick it up.

5. Don't expect to call the office and speak with the doctor in the middle of a clinic day. A nurse can usually handle the question. If not, she'll have the doctor call you back after seeing the scheduled patients. -- GENTLE REMINDER IN SIOUX FALLS, S.D.

DEAR GENTLE: Thank you for the reminders, which may help readers avoid some of the frustrations they encounter when going for a medical appointment. They are well worth the space in my column.

DEAR ABBY: My husband and I have become fond of a delightful elderly couple, "Frank" and "Annie." We bought the home across the street from them 10 years ago. They have four children, two of whom live nearby.

Two years ago, Frank was diagnosed with dementia. They are adamant about staying in the house they've owned since they were newlyweds. This means more of the burden of caring for the house and finances now falls to Annie, who has health problems of her own.

We help out whenever we can, because I know money is tight for them. When their lawnmower broke, we bought them a new one, and with the help of another neighbor, we take care of general yardwork and house issues.

I am growing increasingly concerned about the state of their finances, and bewildered that their children never seem to help. They interact with their parents at birthdays and on holidays. I don't know the children well, but is there a way to help them understand that their parents may not be volunteering all their troubles?

Frank and Annie are proud of what they've accomplished, but now they need a little extra support. They never ask for help, but gratefully accept it if it's offered. Would I be out of line to communicate with our neighbors' family? -- LOVE THY NEIGHBOR

DEAR LOVE THY NEIGHBOR: Out of line? Not at all. The "children" should be told about your concerns, and also the various things you and the other neighbors have been doing to help their parents. Sometimes the children of aging parents don't recognize the subtle changes that take place when a loved one has dementia. Bring it out in the open, and you'll be doing all of them a favor.

DEAR ABBY: I have been married to "Roman" for 13 years. He has always been a man of few words who didn't initiate much on his own, so I stepped up to bat and did everything. I took over all aspects of our married life -- from bill paying to home maintenance to romance. He would tell me how grateful he was to me for doing it.

His adult daughters from a previous marriage have always been cold to me, and I recently found out why. It turns out Roman made up horrible, untrue stories behind my back. He painted himself as the victim of abuse! His daughters staged an "intervention" to save their dad, and Roman went along with them. He cleared out our bank accounts, hid money and assets and filed for divorce. I was stunned.

Abby, he went along with the charade for a week -- until his guilt got the better of him, and he admitted he had made it all up. He claims he doesn't want to divorce me after all. He said he made up the stories to get his daughters' attention.

Roman and I are now going through counseling, and I am assuming responsibility for my part in this mess. He harbors strong resentment toward me and resorted to passive-aggressive revenge. We're both doing our best to establish forthright, honest and open lines of communication.

The problem is his daughters still believe the lies. They hate me and won't speak to their father unless he divorces me. I'm not sure what to do. Roman has lost his family and he may lose me, too. The damage is so widespread I don't know what can be regained. Have you any advice for me? -- OLDER, WISER AND HEARTBROKEN

DEAR OLDER, WISER AND HEARTBROKEN: Your letter made me furious. It proves that with your husband no good deed goes unpunished. Had you not taken on the functions your husband avoided, your credit would be shot, your house would be a wreck and your sex life nonexistent. And for this your husband slandered you?

That he would lie to his daughters about you is disgusting. That he then made a money grab and hid assets is appalling. What have you to gain from continuing this marriage? If I were you, I'd contact a divorce lawyer and a forensic accountant, divide the assets and let the daughters take care of their ingrate of a father.

DEAR ABBY: My husband and I belong to a supper club comprised of four couples. We have enjoyed our monthly gatherings for years and have developed a strong bond with each couple. As a rule, each one takes turns hosting the event in their home. The recent behavior of one hostess has us baffled.

For starters, "Lynn" sometimes seats herself and her husband at a separate table, even though there's room at the main table. She also involves herself with activities I consider rude -- taking calls on her cell, perusing Facebook, doing paperwork. It's beginning to feel as though we are an obligation rather than wanted guests.

Members of our group have been hesitant to discuss this with her because we don't want to create tension in the group we have come to hold dear. Any suggestions? -- GETTING SERVED A COLD DISH

DEAR GETTING SERVED: It appears there is already tension in the group you have come to hold dear. For a host to behave the way Lynn has is rude. Whoever in the group is closest to Lynn should have a chat with her about it -- preferably face-to-face -- and ask her to explain. It's possible that the responsibility of hosting has become too much for her.
