DEAR MISS MANNERS: We have some friends who live eight hours away, and they have been after us for the past few years to visit. A few weeks ago, we made the drive to see them and stayed two nights.

Both mornings, they slept very late, rising after 10 a.m. We got up and made coffee, and that was the extent of the breakfast. We took them out to a restaurant dinner one night, and the next night, they ordered pizza and passed out flimsy paper plates.

We left the following morning, after we again had made the coffee. They did pull themselves out of bed to see us off. We stopped at a fast-food restaurant to eat.

It felt disrespectful to me that we were not worthy of them getting up at a reasonable time, perhaps actually cooking something and, that aside, using something other than paper plates. The two of them are also constant quibblers.

We are considering not making the effort to see them in the future. Am I being too picky and snobbish, or expecting too much?

GENTLE READER: It is a very different thing to live with someone -- even temporarily -- than just to know them socially. Your friends have a home routine that does not meet your expectations, and while it does not make them great hosts, it does not necessarily make them bad companions.

Miss Manners suggests that you keep the friendship away from overnight visits. Unless, of course, you want to act as hosts next time and show them how it is properly done. Just be prepared for them to sleep through your homemade breakfast served on china plates.

DEAR MISS MANNERS: Is it a requirement to bring a gift to an engagement party when a gift registry is not included in the invitation?

GENTLE READER: It is not even a requirement when it is.

DEAR MISS MANNERS: I’m wondering how to address my 10-year-old granddaughter when she says things that are unkind to me.

She has a habit of putting down her younger brother (saying he’s stupid, lazy, fat, etc.), for which I’ve admonished her. We’ve always had an excellent relationship, but I notice she’s now directing these types of comments my way, particularly about my innate physical characteristics. (She comes from a family of great beauties, and I’m not overly attractive.)

I’m reluctant to give her the power of knowing she can wound me, but I’m not quite sure how to handle this passive-aggressive behavior. Suggestions?

GENTLE READER: Yes, two. First, that you recognize that this behavior is aggressive-aggressive, not passive-aggressive. And second, that you dissuade yourself of the idea that the power is hers if she knows she can wound you.

Miss Manners hopes that at 10 years old, this child is not beyond learning empathy -- or at the very least, the consequences of damaging relationships. As her grandmother, you have the standing to tell her that this is hurtful and that insulting people is not acceptable.

You may add that others -- e.g., her friends -- may not give her the second chance that you will.

DEAR MISS MANNERS: In my grandparents' home, no food was allowed to go to waste. After a meal, if there was any food left on someone's plate, it would either be claimed by someone else or added to the soup pot that was always on the stove. If someone had gravy left on their plate and no bread to sop it up, they were allowed to lick the plate.

This was because my grandparents had left Europe to escape famine; wasting food was a matter of life and death. So manners are situational as well as cultural.

Knowing this, if you are a guest in a home representing an unfamiliar culture, would it be smart to discreetly ask the host or hostess if there are any special manners expected of you? You could do this at the door while you thank them for the invitation. If you were invited by a friend, should you ask them ahead of time?

GENTLE READER: No. And Miss Manners fears the consequences of inviting every hostess to improvise new rules for hungry guests at the front door.

But you cite an interesting example. Current dinner guests of your grandparents should not be considered disrespectful of your grandparents’ life experience if they expect any licking of plates to occur out of sight.

DEAR MISS MANNERS: I have never had a good memory, and now, in my 70s, my memory could be classified as poor.

I just invited a friend to see "Dune 2" with me, and he reminded me that he had declined to join me for the original "Dune," so why would he want to go to the sequel?

He did attach a laughing emoji, but it still stung.

At a different friend’s house, I admired some brickwork and asked who had done the installation, because I need some similar work done. She reminded me -- making her annoyance clear -- that I had asked before, and that she had told me the person no longer did that kind of work.

In both of these cases, I apologized for my poor memory. But I wonder if there is a way I can remind people that these memory lapses aren't really my fault, and that the kind thing to do is let them pass.

GENTLE READER: Your second friend was just being rude, and the proper way to acknowledge that is to make your apology perfunctory.

But are we so sure your friend with the emoji was not trying to be funny? Miss Manners suspects he did not really expect you to remember his having turned down an invitation to the original "Dune," which premiered 40 years ago. Even if he was referring to the more recent film, it might have lightened your own mood to answer, “I thought that after 40 years, your tastes might have changed for the better.”

DEAR MISS MANNERS: I moved to a new area and adopted a large dog from a shelter. Large dogs were common where I grew up, and while some people didn’t care for dogs, very few people were scared of them.

In this new area, I’ve noticed that some people are outright afraid of my dog. While on a walk, I saw a mother gasp and clutch her toddler to her chest to keep him out of the dog’s path. One neighbor literally screamed when the dog walked past her open door. (The dog was ahead of me and she did glance into the open door, so I suppose the woman didn’t see the leash and thought that she was loose.)

A grown man stepped off the elevator when we entered, saying he would take the next one and flattening himself to the wall to keep his distance as he did so.

How should I react when someone is scared of my dog? I obviously feel bad for scaring people, and my instinct is to apologize and remove my dog from the situation. I will continue walking her away from people who are clearly uncomfortable, but are apologies necessary when neither my dog nor I are doing anything wrong?

Is there a phrase you can suggest to convey that I’m sorry they’re feeling this way, without implying any wrongdoing?

GENTLE READER: Moving to a new area always involves a period of adjusting to local custom. Unless your pet is the size of a bear, the three reactions you describe are suspiciously dramatic -- and therefore worth investigating further.

Has the (supposedly) grown man, for example, chosen an unfortunately childish way to alert you to a building rule of which you were unaware, concerning pets in elevators?

Once you are confident that you are not violating any unfamiliar rules, you will still have to account for the fright: “She’s harmless; there is no need to be afraid.” But Miss Manners will agree that this may be said a trifle stiffly if you believe the dramatization of said fear to be out of proportion to the actual emotion.

DEAR MISS MANNERS: My husband is in a rehabilitation facility, receiving physical therapy to improve his strength after orthopedic surgery. He is in a semiprivate room. His bed is by the window; the other bed is by the door.

What is the proper way to pass by the other man’s bed to get to my husband’s? Should I avoid looking at the other patient? Look and nod? Look and greet?

GENTLE READER: The etiquette of the semiprivate room in a medical facility requires a delicate balance between familiarity and distance. One can hardly pretend the other person is not there, so initial introductions and greetings are in order.

But it is also necessary to provide a level of privacy -- looking away when necessary -- that does not, in fact, exist. A brief “Good afternoon” (if the patient is awake) will do as you move past. Think of it as the psychological equivalent of the fabric curtain drawn down the middle of the room -- a barrier that has to be believed to be seen.
