DEAR MISS MANNERS: One of my novels received a prestigious award. Upon learning this from a mutual friend, an acquaintance approached me and said, "Congratulations, but what a shame this didn't happen years ago when you were still young enough to enjoy it."

I gathered my 70-year-old wits and politely thanked the person without apologizing for my failure to achieve success earlier in life. Since then, two other people have expressed similar sentiments.

So far, I've held my good manners in front of me like a shield, but I wonder if there is a polite way to respond to the negativity implicit in these statements. You are my guiding light of good manners. If you say it is best to continue to respond to the congratulations and ignore the rest, I shall do so.

GENTLE READER: The optimists among us are inclined to think these speakers are well-wishers who think you should have gotten the award sooner, but do not know how to express themselves tactfully.

The pessimists will see the phrasing as an insult.

Since at least one speaker was only an acquaintance, there may be no way of knowing which was actually intended, but the response should be the same: Treat it as a joke -- not the laugh-out-loud sort, but gentle teasing.

Answer with a broad smile and say, "Yes, if only it had come before my dotage." This response rewards the tactless well-wisher. But it also punishes the person who intends insult by refusing to accept it.

DEAR MISS MANNERS: I was in a museum cafe, searching for a place to sit with my husband. There were two remaining tables, but no chairs.

A lovely father and son at one table saw my dilemma and immediately offered me their spare chair. I then turned to a woman at the table on my other side, who had two empty chairs, one of which was holding her purse. I said, "Could I borrow one of your chairs?"

She said, "No, my husband is coming."

I replied, "Will the two of you be needing three chairs?" looking at the chair that held her purse.

She said "no" with a flounce, and hung her purse over her own chair, allowing me to take it while glaring at me.

Was I rude to push for the chair? Or was she rude to think a chair for her purse was more important than a chair for a person?

I see people doing this all the time -- on crowded trains, in airport lounges and other places. How can they look around a crowded room with people standing and think their purse or work bag is more deserving of a seat?

GENTLE READER: That extra chair is seeing a lot of action. You were not rude to ask for it, but the woman was rude twice: when she refused to give it up the first time and again when she flounced about it.

Perhaps the chair has some thoughts on why the woman thinks her purse is more deserving than yourself. Miss Manners cannot help with that one.

DEAR MISS MANNERS: My new ophthalmologist is a 35-year-old man whom I have known since he was 8 years old and I coached him in youth football. He was in my son's class, and I had frequent contact with him through his school years until he left for college.

So I saw him in the office and I said, "Dr. Smith, how good to see you." He insisted, "Just call me Tommy."

Inside his office, I feel uncomfortable addressing him as anything other than "Dr. Smith," so now I avoid calling him by any name. I feel awkward, but I understand his job requires the honorific.

Manners are supposed to help people feel comfortable, and in this case, the opposite is occurring.

GENTLE READER: Making people feel comfortable is not always the goal, but we can start there.

Dr. Smith may have graduated first in his class, but the use of the honorific by someone who once exercised authority over him could be making him uncomfortable. So whose comfort should we consider?

However, there is a much better reason than comfort to be using his title. Someday he may have to discuss a serious medical condition with you. If that day comes, you do not want to waste time wondering if the little boy who got confused during the final game and scored a touchdown on his own team was also looking in the wrong direction on the day they were teaching glaucoma.

Of course, you cannot say that. So Miss Manners' suggestion is to ask Dr. Tommy if you could use the title in the office -- citing as an excuse both that you are old-fashioned enough to do that with all your doctors, and that you are so proud of him.

DEAR MISS MANNERS: Tensions were riding high on the eve of my brother's wedding, when I made the faux pax of mentioning his baldness at the dinner table. I mentioned that I, too, have male-pattern baldness (I am female).

He has been bald, mind you, for 15 years. Had he said, "I am sensitive to my lack of hair, and I'd appreciate it if you would not mention it ever again," I would have obliged. I also would have apologized for having touched upon his sensitivity, which I knew nothing about.

Instead, he explained to me how I had been out of line, that one does not mention these things, and on and on, ending with the honor he had bestowed on me by asking me to be his witness at his civil ceremony. By the time he was finished, I felt shamed and unwelcome. Was my indiscretion in such poor taste that I deserved a public rebuke?

GENTLE READER: The night before a wedding, the table in question is often at the rehearsal dinner. Miss Manners is dearly hoping that you did not think that his baldness was an amusing topic for a toast.

If so, it would not excuse your brother from delivering a public rebuke, but neither should it be thought to exonerate yourself.

DEAR MISS MANNERS: I have a friend I've known for over 30 years. We're both retired. I'm married, she isn't. I keep very busy with a big house, rescued animals and projects I like to work on.

I'm not much for talking long on the phone, but I don't mind texting, because I can reply when I have time.

The last couple of years, this friend has become increasingly annoying with her phone calls. If I reply to texts in rapid succession, it's like an open invitation to call me. She'll talk for hours about the quilts or the loaves of bread she's made.

She posts things on social media that should be kept private. It's so embarrassing, some of the things she's posted. I've noticed she's not getting too many "likes" or comments, so I hope she's taking the hint.

I've learned to not answer her texts right away. I'll wait hours sometimes. I'll say something about being busy or tired and going to bed soon, and next thing I know, she's calling.

I tell her that my phone isn't working right, or that it was on the charger and I wasn't nearby, but I can only do that so many times. I couldn't sleep the other night, so I got online and I happened to post something I thought was funny. I'll be doggone, she saw it and texted me! I have everything set to "private" but she could see I was awake. I ignored her.

The last straw was when she threw her two cats outside. One ended up dead in the neighbors' yard, and who knows what happened to the other one. I think the first one was poisoned, from what she was telling me. She didn't seem to care. I love animals and feel she was wrong to do what she did.

I feel like a snob, but I don't have time for her mundane conversations just because she's bored and I'm not. I can go back and forth texting other people all day, and we enjoy it without bothering each other with phone calls. I think I'm just looking for validation that it's OK not to respond to her each time.

GENTLE READER: And you are maintaining this friendship because ...?

Those 30 years, of course. Indeed, it is kind to tolerate longtime friends who have become lonely and boring.

Miss Manners is not one to attribute all poor behavior to medical problems and to excuse it on those grounds, as many free-range diagnosticians do. So let us first address the common problem of setting limits on friends who intrude on one's time.

The simplest solution to those telephone calls is to explain your and your other friends' habit of conversing only by text, and to say that such has become your policy. It is, in fact, an increasingly popular way of curbing the immediate demands of the telephone.

Then never pick up. And certainly never tell this person anything that you don't want to be made public.

But the cat incident is alarming, and not only because of its cruelty. It does seem time to express concern about your friend to those more closely responsible for her welfare.
