DEAR MISS MANNERS: Your mom mails you a birthday card. She has no way of knowing if the card arrived the day before, the day of, or the day after your birthday. (She is not the mailman.)

She assumes it arrived before or on the day of your birthday. Is she obligated to call you on your birthday, or by virtue of her sending the card, are you now obligated to call and thank her instead?

Basically, it's "I sent the card, so now he needs to call me so I can wish him a happy birthday."

And if you don't call them to say, "Remember it's my birthday" they get miffed.

GENTLE READER: Then call them. ("Them"? How many mothers do you have?)

You cannot seriously expect Miss Manners to come up with a rule about the timing of irascible courtesies. And even if she did, someone who is looking for an insult while in the very act of conferring good wishes is not likely to be satisfied.

A more relevant rule is: If you can placate a difficult relative with a trivial concession, do so.

DEAR MISS MANNERS: My fiance would like me to make his sister a bridesmaid, and I would love to do so as well.

However, my future sister-in-law loves to dye her hair every color of the rainbow and has many large, visible tattoos. While I accept and love that free-spirited part of her personality, I would rather not have colorful hair and tattoos prominent in photos that will last a lifetime, especially as she would be the only member of the wedding party with such features.

Would it be rude to request natural-colored hair and makeup covering her tattoos for the wedding day? How should I phrase this wish? I do not want to erase her individuality, and especially do not want to come off as a bridezilla.

GENTLE READER: But that would be erasing that individuality you profess to accept and love. And a bride who wants to remake others into matching background figures for her wedding album meets the definition of a bridezilla.

Besides, Miss Manners assures you that your photographs will mean more if they represent people as they are. If your future sister-in-law becomes more conventional over the years, any embarrassment over these reminders will be hers. And your friends and possible eventual descendants will be more interested in seeing real people than they would be in the phony, generic look-alike versions you think you want.

DEAR MISS MANNERS: An acquaintance told me that wearing a watch or other timepiece outside of work (social functions, over for dinner, etc.) was rude. "Watches are for work. Time shouldn't matter when you're with friends," she said.

I have never heard of this. I am ashamed to think I may have been unknowingly offending my friends and family by merely wearing a watch. I would never want them to think that I didn't value my time with them. Is this really rude?

GENTLE READER: As your acquaintance and Miss Manners are the only two people still on Earth who remember this rule, you may assume that you have not offended others. Leftover indignation may be directed toward those who check the time or anything else on their cellular telephones when supposedly socializing.

DEAR MISS MANNERS: For my son's upcoming birthday party, we will be inviting his class and baseball team, as well as a few cousins. He has lots of toys already and doesn't really need any more.

I know asking for cash, or any gift for that matter, is tacky, but since it is customary for people to bring gifts, I thought it would be convenient for us and cheaper for the guests to just give him a $5 bill instead of a toy that would not be used. The money would go into his piggy bank.

Not sure how to word this, though, without sounding awful. Please help. I don't want to offend anyone, but it would be cheaper than an unused $20 toy that we don't have room for.

GENTLE READER: It would also be cheaper for you not to have a party at all. After all, your son has probably had a lot of them already.

Miss Manners finds that practicality does not factor heavily into the rite of passage that is celebrating children's birthdays. However, handing over a fiver as a price of admission seems particularly insulting and takes any small pleasure from the guest in choosing a present.

That is why it sounds awful, even to you. When you have too much of something, the kindly thing is to think of giving things to people who don't have such problems.

But return the toys and keep the money if you must. For goodness' sake, just don't ask for an admissions fee up front, or inform your guests of your intentions -- much less your motivation.

DEAR MISS MANNERS: I used to work at a local farmers market, and one day my boss had me at the front of the stall handing out strawberry samples. One lady I offered a sample to declined, citing an allergy.

In response, I sort of flubbed a quick "Oh, I'm sorry about that," which I regretted saying the moment the words left my mouth. I'm vegetarian, and it always irritates me when people with no experience with vegetarianism pass judgment and sometimes say straight to my face that I must be living less of a life. I'm not "missing" anything, just living differently.

I certainly wouldn't have appreciated it if the words I spoke to that lady had been spoken to me. What could I have said instead?

GENTLE READER: Perhaps you are overthinking this? How long ago did it happen, and do you imagine that the lady is brooding about it?

Presumably you were sorry that you mistakenly offered the lady a strawberry, not that you attacked her lifestyle as inferior.

Miss Manners understands your good intentions and appreciates them, but a simple, "I'm sorry. Perhaps we have something else that you might be able to try" would have sufficed.

She further notes that however noble the justification, there is a difference between choosing to be a vegetarian and being born with an allergy. Miss Manners is not suggesting that anyone apologize for either situation, just that you not confuse them.

DEAR MISS MANNERS: We live in an area surrounded by high-achieving families. Nowhere is this more evident than in the behavior of local parents regarding their precious children.

I frequently have to endure conversations in which the guilty parent always manages to work into the conversation the child's straight-A average, her membership in the National Honor Society, her high class rank or the many top schools that are wooing her. This is always done as a sort of aside, e.g., "She's just so social -- I don't know how she manages to keep up her straight-A average!" or "She got a concussion skiing, but, bless her heart, still is getting straight A's in everything and keeping up her required community service hours for the National Honor Society!"

I am growing weary of pretending to be as interested in their son/daughter as they are. What is a polite response that will shut down the conversation before we get into a lengthy conversation about their child's class rank and GPA?

GENTLE READER: In answering your question, Miss Manners will, metaphorically, be putting a weapon into your hand. She therefore feels a need to preface this with some points about its responsible use.

Some show of interest in the banal conversation of others is required by good manners (although strained smiles are not required if your reaction is invisible because the bore is on the other end of a telephone or a computer). And each new person must be allowed to bore you a bit: that you heard the same litany from parents one through five does not, unfortunately, cut into the allowance you must make for parent No. 6.

Once having listened patiently to the initial salvo, however, you have Miss Manners' permission to pursue your own thoughts -- and to hint slightly (not obviously, which would be rude) at distraction by adopting a glassy look and fixed smile, or surreptitiously glancing around, provided you seem to catch yourself and whip back with a guilty smile.

If prodded for a response, you may sheepishly admit that you missed what was said -- with apologies because it is rude to cease to pay attention -- and quickly open another topic before the parent offers to repeat herself.

DEAR MISS MANNERS: An acquaintance of mine offered to let me use her cake topper and cake server for my wedding cake. She had gotten married a couple of years before me. We were not invited to her wedding.

My fiance and I are just not able to invite her and her husband to the wedding. We only have a certain amount of room at our reception, and we are trying to save as much money as we can.

Would it be ill-mannered to use the cake topper and cake server, even though she is not invited to the wedding?

GENTLE READER: It will certainly not go unnoticed. Since you will be saving money by not including your acquaintance on the guest list, Miss Manners suggests you find other economies elsewhere than the cake accoutrements.
