DEAR MISS MANNERS: I'm a man in a great relationship with another man. We've been together seven years and moved in together six years ago. My family has come to love and accept my partner as part of our family.

His parents are religious and give me the very cold shoulder/silent treatment. We host Thanksgiving at our house and his parents come over. And even though I do everything to welcome them, they are always rude to me (in my own house). His mother will avoid eye contact and does not say hello or goodbye to me. When I approach to do so, she quickly walks away or turns away.

On the off chance that we make eye contact, she never smiles, but she smiles and is very talkative and the "huggy" type with other people who are here for Thanksgiving. When they leave, they hug everyone and even though I'm standing there smiling, she always makes an obvious choice to not say goodbye or thank you or anything to me.

The year before last, I gave her a hug and told her I was happy they came. She left her arms hanging down and didn't hug me back or say anything at all. So now I end up saying, "Thanks for coming" as they walk away ... then feel stupid for giving them the courtesy that they never give me. This has happened the last three years in our house. Would I be out of line to tell them, "If you don't like me, then get the hell out of my house, and I don't give a rat's behind if I never see you again"? I'm furious because I realize I'm holding back harsh words out of respect for my partner. But I have had enough! What do I do?

GENTLE READER: Well, what about that respect for your partner, who evidently wants to continue to entertain his family in what is, after all, his home too? And what about the aspect of your self-respect that has to do with your behaving decently even when others do not?

It is not Miss Manners to whom you should be appealing. Of course she thinks ignoring you is horribly rude; equally, of course, she is not going to countenance your being horribly rude.

But where is your partner in all this? Could he get his mother under control? If not, would he be willing to give up the family Thanksgiving? If he pleads with you to put up with it once a year for his sake, Miss Manners hopes that he is equally forbearing about something that matters to you.

DEAR MISS MANNERS: Could you please tell me how one is to set the table for dinner? I was taught that the silverware is placed on the left side of the charger plate placed on top of the dinner napkin. My wife says that it should be split up, knife and fork on the left and spoons on the right side of the charger plate. The loser has to cook dinner for a full week.

GENTLE READER: You should both put on your aprons. Piling it all on the napkin is wrong, but so is placing the knife on the left alongside the fork.

DEAR MISS MANNERS: Is it appropriate to call another woman's husband a pet name and leave voice mail messages that start off as "Hi, honey"?

GENTLE READER: Yes, if she is either his mother or his mistress.

DEAR MISS MANNERS: When is it allowed for a guest to bring his or her own food or drink to another house? This is in situations where there is no medical issue or allergy involved.

For example, one is visiting one's aunt. She offers tea, but does not have your favorite artificial sweetener. Is it OK to pull a couple of packets of sweetener out of your purse, instead of using her sugar?

Or one is on a diet and visiting a friend. Is it allowed to bring one's own low-calorie, low-fat snacks and produce them when the host offers refreshment?

Or there is an invitation to dinner, but it is possible that the hosts are not aware that one is following a low-carb, gluten-free diet (not a medical need, just a desire to follow this particular diet). How much food can one bring -- appetizers, entree, side dishes? And does one need to bring enough to feed all the other guests, or just oneself?

GENTLE READER: Alas. Miss Manners is reluctant to open up these floodgates by providing solutions to any of your situations -- particularly when it comes to satisfying the changing "needs" of fad, fleeting diets (speaking of floodgates, which are sure to open up at that statement).

It is never polite to offend your hosts with the implication that (in non-allergic or medical situations) your own food is better and healthier for you than anything that they might provide.

Nevertheless, in the name of limiting those angry protests, here are some alternatives to what you propose:

If you want to provide your own packets of artificial sweetener, you may do so, but only if you say something like, "Oh, I'm watching my sugar intake and these new sweeteners are wonderful. Perhaps you would like to try one." But then you must be prepared for whatever lecture your aunt might have about their more serious ramifications, relative to sugar.

It is rude to produce your own snacks when offered refreshment. If there is absolutely nothing you can eat, you may politely abstain. Fill up before you get there.

And no, you may not bring your own unauthorized food, particularly only for yourself, to a prepared dinner party. You are permitted one attempt to offer to bring one item to share with all of the guests, but if it is declined, you must adhere.

How any modern host could possibly account for every single guest's tastes, diets, preferences, medical needs and allergies in this age is beyond Miss Manners. She only asks that they make a reasonable attempt to fulfill the latter two categories, and that guests make their own reasonable attempts to eat something on their plate and not complain.

DEAR MISS MANNERS: I WOULD LIKE TO KNOW IF IT IS APPROPRIATE TO THANK SOMEONE AFTER THEY HAVE ALLOWED YOU TO YELL AT THEM.

GENTLE READER: YES, BUT IT WOULD BE BETTER TO APOLOGIZE.

Oops, Miss Manners should have waited until that truck went by. She suggests that you turn down the volume for the apology -- and all future occasions, other than alerting people that they are on fire.

DEAR MISS MANNERS: When I saw one of my good and longtime friends at a party at another friend's house the other day, she informed me that she was not inviting us to her forthcoming get-together. She explained she is cooking fish and that we are vegetarians.

She also informed me that some other common friends were invited. I know that the spouse of one is also a vegetarian, so being vegetarian was not the reason. She also knew that we were busy and would not have been able to come anyway.

I can't understand why she would make a point of telling me that we were not invited. I find this very rude and I am upset. Should I be?

GENTLE READER: Rather than flattered at being told "Nyah, nyah, you're not invited"?

Miss Manners is upset, too, at the emergence of the negative invitation -- often bridal couples telling people they will not be invited to the wedding -- and she doesn't even know your friend.

Nevertheless, she suggests you focus on the larger issues -- that you have not been excluded from anything you could have attended; that your awkward friend presumably does not want you to feel left out -- and ignore the smaller ones: that some carnivores are married to vegetarians; and that guests should not be excluded merely because they cannot eat everything on their plates.

DEAR MISS MANNERS: I have five grandchildren (two are my daughter's and three are my son's). My oldest grandson is actually a step-grandson, and although he has a good relationship with his biological father and grandparents, he lives full time with my son. He has been my grandson since he was very young and has always called me "Nannie" -- the same as all my other grandchildren.

A friend of mine, who has no grandchildren yet, feels that I am being less than truthful when asked how many grandchildren I have and I answer "five." I feel it is unnecessary to go into a big explanation for a simple, casual inquiry. Who is right?

GENTLE READER: The only thing Miss Manners can find that you are doing wrong is to consider such a heartless busybody a friend.

DEAR MISS MANNERS: We invited three couples to dinner for our 30th anniversary. Are we obligated to pay the entire bill?

GENTLE READER: You are obligated to notify them in advance whether you are actually inviting them, in which case you do not charge, or offering them an opportunity to buy your company.
