DEAR MISS MANNERS: I was taught by my mother and grandmother, who practiced what they preached, that condolence letters are to be acknowledged.

Their practice was to answer every condolence letter with a return letter. It could be long or short, but at the very least it should express gratitude for the sender’s thoughtfulness.

I have followed their practice throughout the decades, and I have found that writing acknowledgment letters has been very helpful to me as I have coped with the grief of losing important friends or family members.

In recent years, however, I have not received any acknowledgment for condolence letters that I have sent. I make it a point to write something thoughtful, including a memory of the deceased and a statement of my appreciation of him or her. I would never send a preprinted, store-bought condolence card.

Should I just face the fact that most people simply don’t write acknowledgments anymore? I’d like to tell them that doing so might help them in their grieving process.

It is also a thoughtful gesture to acknowledge thoughtful gestures, right?

GENTLE READER: Yes, but Miss Manners does not recommend you tell them that. Besides it being an admonishment, it will not help your cause if they disagree.

But if it makes you feel better, you are correct. Condolence letters should be acknowledged, assuring those who care that their appreciation of the deceased and sympathy for the bereaved was meaningful.

Doing so can also offer comfort in recognizing the importance of the life that was lost.

Or not. But it is still the correct thing to do.

DEAR MISS MANNERS: Sometimes I am served something I don’t want to eat, like meat with fat or gristle. I trim my portion and move the trash to the side of my plate -- inconspicuously, I hope.

Once, though, I was served peas that had coarse strings that hadn’t been removed. So I removed them before eating each one.

Is leaving a pile of debris offensive to the hosts or other diners? Does it imply that the cook was sloppy?

GENTLE READER: Perhaps, but it is preferable to choking slowly on pea strings.

DEAR MISS MANNERS: My neighbors have several gatherings a year, and they are always potlucks. If the invitation says, "Bring a dish to share and a bottle of wine," then I am happy to do so.

However, I’m single, and I have noticed that the couples and families also bring only one dish and one bottle of wine. Am I being petty to think this is unfair?

GENTLE READER: Etiquette is not in the business of making everything exactly fair. Unless things are overtly unfair, it is more polite not to notice.

Since the point of the potluck is to share, it feels unseemly to count exact portions. (Perhaps the families do not eat or drink much.) Miss Manners therefore suggests you overlook this injustice and save your annoyance for all of the other ways single people are disadvantaged, inconvenienced and charged more in our society.

DEAR MISS MANNERS: My fiance and I have chosen not to register for gifts. Not only do we wish to do what is proper, but we already live together in a tiny apartment and have neither the need nor the space for additional housekeeping items.

Nor do we wish to crassly solicit money from our guests. And since the wedding is in my fiance's small, remote hometown, which is not easy to travel to, we would genuinely be pleased with and grateful for our guests’ presence, let alone any presents (overused as that phrase may be).

What do we say to guests who inquire about a registry? “We are not registered” feels too blunt, but is adding “Thank you for asking” presumptuous?

I also worry that guests will expect to find registry information on our wedding website, which we have found to be a useful tool for sharing details about hotel blocks and travel. Would it be appropriate to add a note on the site that we are not registered? I could imagine guests waiting for a registry tab to pop up, only for them to feel wrong-footed when one never does.

GENTLE READER: Stop fidgeting, dear.

The website is fine, and saying you are not registered in answer to a question is not blunt if delivered with a smile -- or without, if the same relative is asking for the fifth time.

Now, Miss Manners has a word for the relatives and other guests:

Could you please stop harassing the couple about a registry? They say they have enough stuff and only want the pleasure of your company, which ought to be easy enough to understand.

If you feel compelled to send something anyway, then yes, you will have to spend a few minutes thinking about what they might like. If that is too much trouble, could you at least keep those feelings to yourselves?

DEAR MISS MANNERS: I was dealing with someone who was complaining about a political situation, which he said made him feel very sad and scared. I replied, sincerely, that I was sorry he felt so bad about the situation and I hoped he felt better soon.

Then he complained about “people who say they’re sorry but are really insincere.”

Was there any way to express my sympathy for how bad he felt without agreeing with his view of the political situation?

GENTLE READER: There is, and you already did it. The best way to avoid a fight with someone who appears to be seeking one is not to worry yourself about subtext.

DEAR MISS MANNERS: When attending family events, what is the polite way to decline posing for photos that end up being posted on social media sites without my permission?

People used to put photos in their albums at home, but now they are posted indiscriminately, and it really bothers me. If I want my photo on social media, I’ll post it. Not someone else.

GENTLE READER: Offer to be the photographer.

DEAR MISS MANNERS: When hosting a cocktail hour, how does the hostess gracefully navigate the quantity of food served? For example, if the cheese platter is reduced to a few bites, should the hostess be constantly monitoring and replenishing it, even if the planned “hour” has passed?

I certainly don’t want to appear stingy with guests. But bringing out more food seems to encourage lingering and drifting into dinner time and beyond.

I was taught that as a guest, I should not take the last piece of anything -- crackers, nuts, candy or cheese. Is that still the case? It seems to me that empty platters should signal that it’s time to say "thanks and goodbye." But does it appear churlish to leave the bowls and platters empty?

GENTLE READER: Fill or clear any empty receptacle, in which category Miss Manners includes the guests.

So if Uncle Lance is lingering by the dessert table, hoping for something more, swoop him up and introduce him to any available guest in the next room. Eventually the table will be empty and the guests will get the idea and go home.

DEAR MISS MANNERS: I am currently being treated for a medical problem. The issue is expected to fully resolve in time, but it is temporarily forcing me to work part-time, and prevents me from participating in certain activities that are standard in my line of work.

I therefore have to explain to clients and others that my current availability is limited. I usually give them an abbreviated version of the reason, just so they know that I’m not making something up to avoid doing the work, or to give myself more time to get it done.

Most people just sympathize and wish me a speedy recovery, which is fine. But some interject very religious wishes for me, such as assuring me that “The good Lord is looking out for you and will take care of you for a full recovery.”

This makes me uncomfortable -- first because I don’t appreciate inserting religious beliefs into business transactions in general, and second because I do not subscribe to the same religion as the person making this statement.

I know that people who say this mean well, so I usually just say “Thank you” and try to move quickly to another topic. Is there a graceful way to discourage these comments?

GENTLE READER: Here is a perhaps-novel way to discourage people from introducing their personal beliefs into professional dealings: Don’t you do it first. This includes stating your belief that your explanations may not be believed.

Rather than abbreviate your medical diagnosis, omit it entirely. You can stop talking after saying, “I have a medical condition that temporarily requires me to work part-time,” and Miss Manners thinks you have every chance of being taken at your word.

She cannot promise an instant recovery for the current pandemic of Too Much Information: You may still have to say “thank you” from religious well-wishers and move on. But it is a start.
