DEAR MISS MANNERS: How do I kindly tell my sister that her son’s texts to the family are annoying?

He’s 14, and his texts and phone etiquette leave us scratching our heads. He doesn’t “read the room,” often sending gifs and memes more appropriate for his friends than a family chat that includes his mom, aunts and grandparents. Or he will call several times in a row, then call us mean if we don’t answer.

GENTLE READER: Is there a chance that this boy is trying to communicate with you?

The multiple phone calls and texts would indicate so.

Miss Manners suggests redirecting his misguided attempts by saying, “I’m sorry that I don’t understand the gifs and memes you send, but if you would like to chat or go out for a meal or a walk, I would be happy to do that with you.”

You could initiate this, of course, by answering the phone -- before it gets mean.

DEAR MISS MANNERS: I hosted two couples for dinner at our home that went very well. The next day, I was experiencing some stomach upset and GI issues. I am not sure if the culprit was the food I served, but if so, it may have been that the lettuce was not thoroughly washed.

I texted my guests to thank them again for coming and let them know we enjoyed their company. I also told them about my GI issues and asked if they were experiencing any symptoms, saying that if they were, I apologized profusely.

My husband told me that it was rude to inquire about their health, since we weren’t sure about whether it was the food that made me sick. He also said I “put them on the spot” regarding either confirming that my culinary error made them sick or fibbing to make me feel better.

GENTLE READER: There are ways to inquire about others’ health without going into sordid details. The phrase “GI issues,” for example, need not be uttered (twice, here, making Miss Manners herself rather queasy).

Instead, you may say, “I do hope that you are feeling well after our dinner. I myself felt a bit off, so I just wanted to check on you.”

And make sure that next time, you thoroughly wash that lettuce.

DEAR MISS MANNERS: My partner and I are gay men in our 30s. We are in a committed, monogamous relationship, and we seem to be the only ones. When I’m in spaces meant for queer people and I mention that I’m in a relationship, I often get asked, “Are you guys open?”

I can’t tell if this is a come-on or a simple question, but I can’t stand it.

I have no problem with other people being polyamorous or being in open relationships, but I think it’s tacky to always talk about it or put one’s business out there. It's even worse when it feels like people are pressuring you to break your monogamous ways.

How do I answer this question truthfully without getting offended or coming off like a fuddy-duddy?

GENTLE READER: “No.”

DEAR MISS MANNERS: I’m a member of several organizations. Frequently I’ve sent updates or comments to the leaders of these groups, who then forward my email to everyone with their reply.

Do I need to put a “for your eyes only” disclaimer on each email? That seems a bit stiff, but my emails aren’t necessarily for publication!

GENTLE READER: That you are tempted to add such a disclaimer suggests to Miss Manners that you already know something about the recipients: namely, that they hit Reply All on every email, or that they do not actually read anything that is sent to them. Alternatively, you might not know these persons well enough to predict what they will do with your correspondence.

In either case, a more effective solution would be to ensure that your emails actually are ready for such distribution.

DEAR MISS MANNERS: I treated a friend to lunch, but when we entered the restaurant, she mentioned that someplace else was better. I was a little taken aback and thought it was just an unconscious slip, but then this happened again with a different friend.

What could I have said to indicate that their comments were rude without offending them?

GENTLE READER: It is impolite to tell others that they are being rude, but perhaps Miss Manners can accommodate you by making them feel foolish instead.

Look concerned and ask, in a quiet voice, if they would prefer to go somewhere else instead. As this will likely be occurring while the waiter is walking you to the table, your friend will immediately understand the consequence of answering in the affirmative.

This will only work if having to tell the waiter you are leaving will be more embarrassing for your friend than for you, but she trusts you will know this before attempting the experiment.

DEAR MISS MANNERS: I will be throwing myself a 60th birthday party next year. The only gift I want is the presence of the family and friends I invite to the party. I intend to include “No gifts, please” on the invitations.

All that being said, I realize some people will bring a gift anyway. Some of the people I will be inviting tend to give gifts of alcohol, which I do not want. I do not consume much alcohol to begin with, and I have specific tastes -- I don’t like dry wine, for example.

Is there a way to politely state this on the invitation? Or do I just gratefully accept any gifts of alcohol I may receive, then discreetly give it away later to someone who will enjoy it?

GENTLE READER: It has long been Miss Manners’ policy to discourage invitations that tell guests not to bring gifts -- not because she objects to the sentiment, but because she finds the bald statement of expectation impertinent.

Further appending a detailed list of instructions about what not to bring would be mystifying. The polite solution would be to throw a party -- not, specifically, a birthday party -- at which you can then admit that it is your birthday.

If you cannot do that, then, yes: Give away the gifts you did not expect, and do not want, later.

DEAR MISS MANNERS: I am the janitor at a truck stop. What is the best way for me (a man) to announce myself when entering the women’s restroom to clean it?

I start with calling out, “Hello. Janitor. Is anyone in here?” but it just doesn’t sound right. Some ladies say nothing in response, and if I didn’t look under all the stall doors, I would have walked in on them. Other ladies sound completely panic-stricken, like I’m going to storm right in.

I work the night shift, and there is not another lady on staff to ask.

GENTLE READER: A solution to this is in use in most American airports today, although Miss Manners is unaware of the identity of the clever colleague of yours who first put it into practice.

Acquire a small sign saying that the facility is being cleaned, and place it in front of the entrance to the women's restroom -- then leave it there while you go work on the men’s room. That should give anyone in the women’s restroom enough time to clear out, allowing you to proceed there with a clear conscience.

DEAR MISS MANNERS: I inwardly cringe when I’m given a plant that doesn’t fit with my garden plan. I usually let it sit in its pot for a while and eventually drop it into the compost heap.

Which is the better response: Accept the gift and later compost it? Or tell the person I'd prefer to decline their gift, as it doesn’t fit my plan?

GENTLE READER: The former. The plant, even if its feelings are hurt, won’t be able to tell anyone.

DEAR MISS MANNERS: Whether at home, at another person’s house or in a restaurant, what does one do when food from one’s plate drops on the table?

GENTLE READER: Although she is inclined to think of those as three separate questions, Miss Manners acknowledges a common first step in all scenarios: Do not pretend that it did not happen.

At home, you will likely have to clean it up yourself. At someone else’s house or in a restaurant, you will want to draw it to the attention of a host or waiter. Ask for assistance, but also offer to do the work -- with more or less conviction and insistence depending on the setting, the level of formality and the extent of the resulting mess.

DEAR MISS MANNERS: I’m going to be wed soon and plan to have a receiving line. This will be during the cocktail hour between the wedding and reception, while the venue is rearranged.

Is there a way to politely decline hugging people during this? I’m dreading the mishaps that will occur while holding food and drink, not to mention mussing up my hair. Are two-handed handshakes suitable enough?

GENTLE READER: No and yes. That is, handshakes are suitable, but hugs from the awkward uncle who does not know what to do with his plate -- even if he has not yet had a cocktail -- may be unavoidable.
