DEAR MISS MANNERS: I have been caring for my mother-in-law for 11 years now. Her daughter does not want the job, but I have been doing this because I believe she would not have lasted long in a nursing home.

My mother-in-law will be 96 in March. Her doctor has issued her a bill of good health, and she can easily live into her hundreds.

Is it impolite of me to dislike my sister-in-law for her lack of involvement with the care of her own mother? I really am developing a strong dislike for her selfishness. Is this normal? What is a proper way to express my feelings politely?

GENTLE READER: Etiquette does not dictate how one should feel, only how one should behave. But Miss Manners has made a career out of expressing the former through clever use of the latter.

While outwardly expressing your feelings to your sister-in-law would only escalate hostility (although if your husband is her brother, you might suggest that he do it), you could attempt to alleviate the logistics of the situation by enlisting her help for specific tasks -- a lot of them. The constant requests might make it easier for her to just to initiate participation. At best, you will get some help. At worst, you will have a productive outlet for your frustration.

DEAR MISS MANNERS: I am in my late 20s, finishing a master's program at the same institution where I earned my bachelor's degree, and am in the process of applying for doctoral programs.

A little more than a year ago, I sought counseling for problems I have had since my late teens, and was diagnosed with a moderate learning disability, along with severe depression and anxiety.

Since receiving treatment, I have found the quality of my life and my academic work has greatly improved. My academic transcript will be a part of my school applications, including my lackluster performance as an undergraduate, which I believe can be partially attributed to my undiagnosed issues.

Is there a polite and professional way to convey this to potential schools, without disclosing too much personal information, or sounding as if I am making excuses for my past failures? Or should I remain silent on the subject and just hope that my recent work will indicate to reviewers what my abilities and potential as a student and academic are?

GENTLE READER: Your current record, and commendable instinct to be discreet and not make excuses, seem to Miss Manners to count far more than a blip on your transcript. Professional institutions would benefit greatly from recognizing -- and rewarding -- the difference.

If you are asked directly, or if there is an essay or place to discuss your achievements and goals on your application, you could briefly allude to the discrepancy there. There is no need for going into unnecessary detail. Just say that you discovered a medical condition for which you had to seek treatment, with gratifying results.

DEAR MISS MANNERS: A family member wants to throw a housewarming party for me at HER house to celebrate my new home that is being built. Is this appropriate?

GENTLE READER: It was always Miss Manners' belief that one threw a housewarming party to welcome a few intimate friends to see the new house. As that house will not be able to attend, what is the purpose of the party?

She hopes the answer is not "Presents!" which are properly incidental and absolutely not required. The only events at which the guest of honor is not expected to participate are baby showers and funerals.

DEAR MISS MANNERS: My stepchildren were dropped at our house and sent in with fast food to eat. As there are other children in the household, and as I was raised if you don't have enough for everyone, you don't take it, I sent their mother the following message:

"In the future, please do not send fast food in with the kids. It is very disrespectful to the other kids that live in this house and are limited on the amount of fast food they are allowed."

This message then lead to a verbal confrontation, as she states that I have no right to tell her what her kids can or cannot bring into the house, and that the only one who was rude was me for sending her a message like that. I explained that I will stand up for my children whenever necessary and will not have them being disrespected in their own home.

We try to keep a level playing field in our home for all of the children, but it has been quite difficult. The animosity between the children due to repeated situations comparable to this are making it even more difficult.

Was she in the wrong, or was I, or were both of us?

GENTLE READER: Shared custody is challenging when the parties have already agreed that they no longer wish to share -- that, in fact, the only remaining solution is separate households. But then, that separation should be treated with dignity and the recognition that each parent (or stepparent) is free, within reason, to set rules under each separate roof.

Your dealing with the children's mother may reflect a wish not to put the children in the middle, although the high-horse talk about disrespect -- instead of merely asking if the children could finish their snacks beforehand -- was bound to be taken as a challenge.

The rules in their mother's house allow fast food; those in yours do not. Once you make this clear to the children themselves without insulting their mother, Miss Manners assures you they will figure out on their own how to use the 50 feet from the car to your door to avoid having their fast food end up in the trash can.

DEAR MISS MANNERS: Is it OK to have a female pallbearer?

GENTLE READER: As Miss Manners keeps pointing out about bridal attendants, the important factor is not gender but the tie to the person being attended. So, yes.

DEAR MISS MANNERS: I think someone once said, "I have plenty of friends I don't particularly like," but I am lucky to have only one.

When invited for dinner or other occasions to people's homes, this friend sends a string of photos, complete with texted descriptions and subtitles, from his cellphone to mine.

"Just look at this house!" he exclaims. "Have you ever seen anything so beautiful?" Then, I receive a series of photos of the exterior, the public and private rooms of the house, and even photos of the hosts themselves!

In a recent episode, it was obvious that the hosts were completely unaware that they were being photographed. This occurred while they were preparing dinner, serving wine and talking to other guests in a large, open-plan kitchen.

I wonder what these hosts might have thought, had they known that pictures were being sent to a person they have never met.

It continued in this fashion for part of the evening. "These people," he stated, referring to the other guests, "are all millionaires!" And this was the subtext of yet another series of photos. "They are so rich, they spend part of the year in Europe!"

He also sent a photo of his new car in the owner's paver-system driveway to somehow validate the point that he was in his element.

It seems to me that there are several etiquette violations taking place, but I don't want to violate Miss Manners' rule that I should avoid pointing them out. I have tried all the obvious ways of discouraging this practice, including simply asking him to stop.

Unfortunately, he is aware that I have unlimited service to send or receive photos and text messages. Blocking is not an option. My plea has fallen on deaf ears. What do you suggest?

GENTLE READER: Not inviting this person to your house -- and deleting all his communications without looking at them or responding.

But yours is not the chief problem Miss Manners sees here. It is those innocent people whose privacy is being invaded by a rude guest who worry her. Even if they consented to being photographed for distribution, commenting on their means would be rude.

If she were not leery of adding to this distasteful gossip mill, she would be tempted to forward the material to the victims without comment, so that they could handle the situation if they chose.

DEAR MISS MANNERS: Is there any social gathering large enough to render the use of a cellphone, e-reader, or even a printed book or magazine acceptable? I have the interests of the wallflower in mind.

If no one is clamoring to converse with a particular guest (who is, perhaps, accompanying a spouse), might he or she as well settle down for some light reading?

GENTLE READER: Only if the wallflower's hope is to remain a wallflower, and a conspicuous burden to the spouse. And in that case, Miss Manners wonders, why bother going out to social events?

Guests, as well as hosts, are obligated to help make a party work. And a party in which people stood around waiting for others to clamor for their attention would be pretty dismal. Wallflowers should be out gathering other wallflowers in the interest of making a bouquet.
