DEAR MISS MANNERS: I’m a single working father of four. I’m often given unasked-for parenting advice from female parents who often, frankly, have much less parenting experience in general, and absolutely none with my own kids.

This ranges from comments like, “Children often do better in their mom’s lap” as I’m booking plane seats, to being the only parent on an email chain to get extra tips and help on a class project (e.g.: “Remember to get 10 cheese and 10 chicken quesadillas for the class party!”).

I’m a triple-board-certified physician with multiple advanced degrees from an Ivy League school. I have 54 cumulative parent years under my belt. I can bring quesadillas to a first-grade party.

You point out that using the term “mansplaining” overgeneralizes, so I won’t call this behavior “momsplaining.” What would you call it?

I’m not sure that these comments are always meant in a helpful manner, and many of them seem to imply that men don’t really know how to parent their children. Words of wisdom on this one?

GENTLE READER: Yes, but Miss Manners will credit them to the late Supreme Court Justice Ruth Bader Ginsburg, whose many arguments “on the basis of sex” mandated nondiscrimination for both parents, regardless of gender.

No doubt, these helpful mothers are the same ones who complain that their husbands are reluctant to change a diaper, then snatch it away from them when they “do it wrong.”

A polite, tight-lipped, “Thank you so much for your help, but I think I can handle this” may be your best recourse in the short term. But a reminder that true parental and gender equality mandates that either parent may be similarly equipped to earn a salary, change a diaper and correctly count quesadillas may also be in order.

DEAR MISS MANNERS: My husband and I recently started taking a few remote classes to learn Italian. These are private lessons with an instructor, happening in the morning for about 1.5 hours at a time.

My husband will eat his breakfast during the class if he didn’t have a chance before, during the segment where the instructor is talking. He will also get up to grab things he forgot, adjust the heat, get a sweatshirt, open the window, etc.

I feel that these things are rude, while he feels that they are not, because our relationship with our tutor is semi-casual. I should mention that the tutor does not do any of these things.

GENTLE READER: In the absence of live interactions, we must do our best as a society to approximate them. After all, how do we then justify drinking by ourselves and calling it “happy hour” just because the computer happens to be on?

If you would not eat breakfast or get up during a live lesson (or business meeting or divorce mediation), then the same rules should apply here. Coffee breaks, however, may be used for more than just coffee -- if your husband promises to eat off-camera and adjust the room temperature quickly.

DEAR MISS MANNERS: I have been friends with Elizabeth for almost 20 years. We met because we were both active in an activity our children were in. When we were on equal footing -- both married, working, etc. -- things were fine.

Five years ago, my marriage fell apart in a spectacular way that became the talk of the county. Elizabeth was so supportive during this time. About two years later, Elizabeth began an affair and eventually left her husband.

I supported her when a lot of people didn’t. Cheating was a big part of my marriage ending, so I told her it wasn’t something I would do, but we can be different people as well as friends. She has had subsequent problems, during which I have again tried to be a good friend.

After she moved herself and her children into a house she couldn’t afford on her own, her boyfriend left her. I again tried to be supportive.

Here’s the problem: While she feels like her life is spinning out of control, mine is going great. And it seems like the better I do, the nastier she becomes. I try not to bring up anything positive about my life with her, because then she says things that make me uncomfortable.

It’s getting to the point where I don’t know if I want to be close friends with this version of Elizabeth, which is difficult because we’re both still active in the same activity where we first met. We have moved in the same circles for so long, our lives are very much intertwined.

Do I need to find the understanding from somewhere to continue to try and be supportive, or is it really time to distance myself from my best friend? If it is time, how do I go about doing it without causing any more disappointment or pain in her life?

GENTLE READER: There is a tendency to take offense where none is meant, perhaps to claim sympathy as a victim. Miss Manners is not accusing you of this. She merely notes how surprising it is that people like you accept the premise that your good fortune is a rebuke to her reverses.

It is not, which is why Miss Manners is not charmed by people who admit being jealous of a friend’s happy news. As decent human beings, we are supposed to be pleased by one another’s successes. That baser feelings exist is not a reason to indulge them -- or to reward bad behavior.

There is a world of difference between bragging about something to the point of hurting someone’s feelings, and simply being happy to share one’s good fortune. The former is, indeed, worthy of censure; the latter is supposed to leave you time to show empathy for the less fortunate.

The proper responses to unpleasant remarks by Elizabeth are silence and a change of subject. If this does not discourage the behavior, then it may indeed be time to back off the friendship, while remaining on polite professional terms. This can be accomplished by the same pauses applied on a larger scale -- namely, calls less frequently returned, and finding that you have less time to spend with her.

DEAR MISS MANNERS: At a time when young college students were already becoming intolerably rude in the classroom, virtual teaching has brought them to new lows.

Students have sent me hectoring emails -- some making various demands (in all caps), some outright attacking my professionalism. One parent actually emailed the university president with what amounted to an overreaction to her daughter’s struggles in the class. Reminders of proper netiquette have not improved this behavior.

GENTLE READER: History does not record that the invention of writing was accompanied by a rash of intemperate cuneiform proclamations later regretted, but it would not surprise Miss Manners to learn that it was so.

We are, as a species, strangely apt to forget the recipient of our communications when they are not staring us in the face.

What is quickly discovered, after the initial shock of each new communication technology, is that its permanence -- the ability to share it with the human resources department -- can be used to curb misbehavior. Ethan cannot deny his own words when they are right there in stone or clay or print or your inbox.

Miss Manners is confident that your university has written policies about respect and civility, although she cannot promise anyone has read them. If gentler corrections have failed, remind students -- and, if necessary, their parents -- of such policies, adding that you hope not to have to forward their correspondence.

DEAR MISS MANNERS: A very good friend of ours is getting married in a couple of weeks, after a postponement because of the pandemic. The guest list has been cut in half because of restrictions, but she REALLY wanted us to be there, and we agreed.

We are feeling hesitant about going, as we are older. But we feel that we have passed the time when it would be acceptable to send our regrets, since she has paid for food.

How should we proceed? Wear masks and keep our distance from everyone as much as possible? There will be a meal provided, so people will have their masks off to eat. We are struggling to know what the right thing to do would be.

GENTLE READER: Let us first agree that the most worrisome problems, if you decide not to go, are the rudeness of rescinding an offer after you have accepted it and the hurt it will cause your friend -- not the quantity of leftover duck breast.

Miss Manners constantly rejects the modern tendency to justify every whim in the name of medicine, but her objections do not extend to actual health risks. Failure to attend when you are sick is not rude, nor is staying home because doctors say that you are more susceptible to a virus that is wreaking havoc worldwide.

Whether you choose to exercise this option is a question for you, not etiquette. If you decide not to attend, call your friend and convey your great sorrow and remorse. Were she less aware of the contributions and sacrifices of the medical community during the pandemic, Miss Manners might have added that you could blame your absence on your doctor’s over-solicitousness.
