DEAR MISS MANNERS: My son graduated from high school back in May. We sent a number of announcements to close friends and relatives. We also invited those in our city, and those traveling here for the graduation, to a get-together to celebrate.

Most people who received the announcement and/or the invitation bestowed gifts or money on my son. However, one such person did not, and although I've never said anything to her, it bothers me.

This same person has attended at least four barbecues/parties at my home, where my wife and I provided everything. She and I participate in a morning exercise class along with several other friends, and have done so for years. She and her husband have considerable means, as they show with their worldwide travel, stays at five-star hotels, and very expensive house, cars and wardrobe. He is a doctor, she is a nurse, and they do not have kids. Never once have they reciprocated with an invite to any function at their home or to a dinner out.

She was the only person not to give my son a gift or card. Do I just keep this to myself, or ask her why she chose not to provide a gift?

GENTLE READER: Exactly why did you invite this person to your son's graduation? Is she a friend of his?

She is not a friend of yours, as is evident in the way you speak of her and her husband. And they have never cared to entertain you.

Sadly, you have supplied the answer: You have noticed that they have money, and you were counting on your son's getting some of it. Demanding payment would be a good way to turn these non-friends into enemies. And Miss Manners reminds you that they know where you live.

DEAR MISS MANNERS: Lately, I have had two separate co-workers express regret that they wouldn't be able to attend a meeting because they needed to assist an elderly parent who isn't doing well.

Having received that knowledge, what should I say to them when I later run into them in the office?

On the one hand, I want them to know that I have sympathy and care about the status of their parents, but on the other hand, I don't want to bring up a painful subject that they might not want to think or talk about. I really don't know the proper etiquette in this situation.

GENTLE READER: That sympathy might remind the unfortunate of their problems is one reason people avoid expressing compassion, even after a death. And the avoidance then creates the feeling that nobody cares.

You can trust Miss Manners that people remember their troubles. As these co-workers have told theirs to you, you should at least express the hope -- as they are able to return to work -- that their parents are better.

You should especially do so if you suspect that the repetition of the identical excuse from different people means that it is just a new excuse for getting out of meetings.

DEAR MISS MANNERS: When showing people around your house, and you come to a staircase, who goes first? The guest or the shower?

GENTLE READER: By "the shower," Miss Manners assumes you mean "the one who is showing the house" and not "the plumbing stall that is curiously being pushed up the stairs."

The old-fashioned rule was that a lady would precede the gentleman up the stairs in case she were to fall -- ensuring that he could then assist her.

In this case, however, and no matter the gender, Miss Manners picks the shower to go first. This has the benefit of reducing the number of times one must say, "No, you want to go to your left at the top of the stairs. No, left!"

DEAR MISS MANNERS: Over the years, I have participated in all my family's and friends' weddings, showers and birthdays. My husband and I don't have children.

My cousins are now starting to invite us to their children's baby and wedding showers. I will never be able to retire if I start another generation of gift-giving. What do you suggest?

GENTLE READER: That you tell your family to cease procreating immediately.

DEAR MISS MANNERS: Several old friends and I have planned a girls' weekend at a world-famous music festival in a beautiful city this summer. But one of the four recently insisted, in a group text, that she did not want to spend her valuable dollars on things she doesn't care for -- namely, classical music, opera or chamber music. These are the focus of this festival and the reason we chose that particular weekend.

I mentioned that the festival includes jazz and blues, and she responded that she had recently attended the best jazz festival in the nation.

No one else responded to what seemed, to me, like a line drawn in the sand. What am I to do?

I am a one-glass-of-wine person, and thus don't favor what I think this friend has in mind: a bender or "party hard"-type of weekend, with evenings spent ordering a lot of expensive food, cocktails and wine at restaurants, followed by more drinking at the city's bars.

I would like to attend one of the festival's events each night, preceded or followed by dinner (with a normal amount of drinking). I actually don't know what the others want. Should I just make up an excuse not to attend?

GENTLE READER: Not before trying to salvage it for yourself and your other friends: "I am so sorry that you are having second thoughts about the weekend's activities, but we specifically chose this time and location so that we could attend the concerts. If you still want to attend, we are happy to meet you before or afterwards for meals or a drink. That is my proposal, but I'll let the others weigh in."

At which point, Miss Manners has little doubt that the rest will follow suit. Or you will be divided and can split off. Or at least you will have your definitive answer and a reasonable excuse not to attend.

But you should not feel coerced into doing something you do not wish to do when you all had decided that this is what you wanted to do. Surely your friend can enjoy her bender elsewhere.

DEAR MISS MANNERS: I don't list my birthday on social media because I don't want it recognized. Somebody wished me a happy birthday on my page anyway, and only four people responded. Embarrassing to no end! However, I can see that the post was viewed by at least 20 of my family members, who did not respond.

My irritation is that these same family members will send me birth, graduation and wedding announcements, requiring me to give a gift. I think it was insulting to not at least write a line wishing me a good day.

How should I now answer their own announcements?

GENTLE READER: Uh. What happened to not wanting to have your birthday recognized?

Is it possible that those 20 family members knew that you do not like birthday attention and were merely adhering to your wishes? Or is it just more fun to resent their acknowledging their own milestones -- considering them blatant gift grabs and unseemly cries for attention -- because you would never stoop that low?

Regardless, Miss Manners does not suggest that you have to reply to their announcements -- just that you appreciate the irony.

DEAR MISS MANNERS: I am fortunate to be invited to many showers (baby and wedding) for younger family members. I am elderly and on a very limited income. I don't have any skills such as knitting, crocheting, etc.

Could you please suggest some gifts that would be welcome and appreciated, but that would also be affordable?

GENTLE READER: Shower presents should be, by their very nature, affordable. So the only real trick here is to ignore the inevitable and persistent registries and financial requests.

Miss Manners recommends bibs, diapers and onesies for babies -- and maybe for newlyweds too, depending on how much they plan to overdo it at the various wedding parties.

DEAR MISS MANNERS: What are your thoughts on wedding gifts for second, third or fourth marriages?

For a second marriage, I myself do not send a gift, just a "best wishes/congratulations" card. For a third, fourth, etc., I do not send anything or attend.

GENTLE READER: Why? Are you protesting?

Admittedly, it can be exhausting and expensive to support multiple attempts at marriage that you feel certain are doomed to fail. But as these matrimonial optimists are presumably friends and relatives, not even acknowledging their weddings seems to Miss Manners a bit callous.

She assures you that a "best wishes" card does not signify condonation of the union. But it also does not justify saying "I told you so" -- even if that is warranted.

DEAR MISS MANNERS: I moved into a new building with a call box and common entry. For first-time visitors, I typically meet them at the common entry to either show them into my home or see them off at the end of our visit.

Once they transition to repeat visitors, though, would it be considered polite to continue to walk back to the common entry with them? Or is just seeing them in/out the door of my second-floor home OK?

GENTLE READER: The latter is fine. Although double-checking that the entry is adequately lit is always kind. Especially if they have enjoyed a few drinks with you before departing.
