DEAR MISS MANNERS: When I was 22, several dear friends were kind enough to send gifts when I participated in a debutante ball. I thanked them all in person.

However, I am now 30 and have failed to send written notes. I feel terrible about this and have for years, but I am uncertain if sending notes at this stage would simply remind them of the insult.

GENTLE READER: Penning a few notes at the time would have been far less work than fretting about it for eight years, a fact of which you must now be aware. Miss Manners mentions this for the benefit of those who complain that their lives are too busy for gratitude.

While etiquette does not have a statute of limitations, your friends are unlikely still to be thinking about your omission. Sending thank-you letters now is more likely to frighten than to atone: Your friends will either worry about either your mental equilibrium or their own postal service.

That you are still worrying over your slip suggests that it has not recurred. The next time you express gratitude to one of these friends for a new gift, include a light-hearted reference to the original gift and mention that you still remember it with affection.

DEAR MISS MANNERS: As a freshman at my dream university in another state, I want to notify close family members and friends of my change of address, but I'm unsure of how to do it.

I don't want to post the information freely on social media. My older relatives don't have Facebook anyway, I don't check my own account that often, and there is always a concern about privacy and safety.

I thought about sending short, personal notes including my new address and how excited I am about college, but a friend told me that the idea seemed "desperate" and like I was "begging for gifts and money."

I hadn't even thought of it that way, and I don't want to make anyone feel obligated to write to me or send me care packages. I just wanted to make sure they had the option if they wanted it. What is the best way to notify a change in address without seeming "grabby" for gifts?

GENTLE READER: Assure your friend that those in search of gifts are not so subtle as to disguise their request as a change of address notice. As Miss Manners is sadly aware, they specify the item -- or items -- they want, the store at which it is to be purchased, the amount the giver may expect to pay for it, the color and the delivery method.

And they rarely trouble to write personal notes to their targeted benefactors. That is what you could do, when you send your change of address.

DEAR MISS MANNERS: I have now reached the age when service people find it amusing to say, "Can I help you, young man?" -- the joke being that I am obviously not a young man.

Would it be rude to reply by saying, "Yes, thank you, handsome" (or "beautiful")?

GENTLE READER: It took Miss Manners a minute to get this, and your service people may take it at face value. But she congratulates you on a comeback that meets her requirements of making your point without being rude.

DEAR MISS MANNERS: While my husband, young son and I were dinner guests at a couple's home, the man in the couple -- in front of my husband and his wife -- complimented what I was wearing, saying that it "accentuates the right places."

To be clear, the outfit was not low-cut or revealing. I simply said, "Um ... thanks" and looked uncomfortable because I really didn't find the remark appropriate.

A general "I like that outfit" or "You look nice" would be one thing, but to add that said outfit "accentuates the right places" was another, especially from a married man (and old enough to be my father at that) to another man's wife.

My husband told me later that he thought the compliment was questionable, but at the time, he just let it pass.

The man's wife was obviously not happy with her husband's remark. But instead of saying anything to him about it, she was snippy with me for the rest of the evening and lectured me on my child-rearing.

Should such a situation arise again, what would be the best way to deal with a host who says something mildly inappropriate -- while I would still be a good guest?

GENTLE READER: Considering that the husband was lewd and the wife snippy, Miss Manners doubts that the situation will arise again with this particular couple, whom you can cross off your visiting list.

Should you encounter such a remark again, you could exclaim, "I didn't know that you used to be a tailor!" As soon as he denies this -- and before he has a chance to say that he was referring to your figure -- you should add, "That's too bad. A good tailor is hard to find. Does anyone know one?"

DEAR MISS MANNERS: Do you send an anniversary card to a couple who are separated?

GENTLE READER: What would it say? "Happy anniversary, each in your own way"? "Hope you make it to the next one"?

Miss Manners would consider it more tactful to ignore the occasion.

DEAR MISS MANNERS: I have always been under the impression that showers should never be given by immediate relatives of the honoree, lest the family be seen as "grubbing" for gifts. Instead, showers should be given by dear and generous friends.

I know that this notion is often ignored these days, but is it still nonetheless true, or am I just too old-fashioned?

GENTLE READER: Only if you think that dignity is a fashion.

Etiquette rules that have an arbitrary connection to the underlying principle of manners sometimes change. For example, a lady who allows her ankles to be visible is no longer considered lewd.

However, the rule you mention has a direct relationship to the moral imperative against soliciting on behalf of one's family. It will not change, no matter how many people disobey it.

When legitimate changes do occur, you may be sure that Miss Manners will inform you.

DEAR MISS MANNERS: I have been friends with a couple for almost 20 years now, and I count them among my closest of peers. They have a 2-year-old child who is an absolute doll, hilarious and cute all the time.

Time has become somewhat of a rarity for us over the past years, and we attempt to have a semi-monthly get-together for a few hours, where we eat, chat and hang out. But now they have begun potty training their son, and while I am over, they will allow him to run around the house wearing only a shirt, and encourage him to bring his potty into the living room with us, and pee or poo when necessary.

I brought up my discomfort with this with them once, but I was firmly rebuked and told that was how it was going to be until his potty training concluded.

While I agree it is their house and their "rules," I confess I am not particularly interested in going over again next week, knowing the situation I will be in. How should I inform them that I won't be coming over, in a way that is both honest but the least offensive possible? Also, am I wrong for feeling uncomfortable in this situation?

GENTLE READER: No, but it is not for you to express this discomfort. Miss Manners need hardly point out that when you shared it the first time, it was not received well and didn't solve the problem.

There are disadvantages to being treated as an intimate member of the family. But the good news is that surely this is a temporary situation. If you feel that you simply can't stand it, wait for a few weeks to see these friends again. And hope that they -- or you -- don't have a child again soon.

DEAR MISS MANNERS: What is the proper number of times to wipe your mouth while eating a sandwich?

GENTLE READER? As many times as it takes to get the mayonnaise off your nose.

DEAR MISS MANNERS: My partner of 20 years and I have been together so long that getting married, now that it is legal in our state, almost feels like a renewal of vows. As such, we have opted for a small celebration and are avoiding many of the traditional elements that feel either age-inappropriate or wrong at this stage of our life: There will be no church ceremony and elaborate reception with multiple wedding attendants in formal attire.

Because when we met, being gay and getting married was inconceivable, we find ourselves unsure about etiquette. Some of our issues are probably similar to any more established (older) couple being married.

One thing I am unsure about is, must we have a wedding registry? We need nothing, and our wants are specific and expensive. For us, the privilege of being legally married in front of friends and family is truly enough.

GENTLE READER: Congratulations -- not only on your coming marriage, but on your wish to apply taste and sense to that spectacle of self-aggrandizement and extortion that has become the typical American wedding. Miss Manners finds it sad that wedding greed has become so institutionalized that you question whether it is proper not to tell people to buy you things. Be assured that you have no responsibility for ordering presents from your guests.
