DEAR MISS MANNERS: Is it OK to spoon out the remains of the froth from a cappuccino coffee?

GENTLE READER: Foods that cling to the tableware are always a challenge, particularly as they tend to be the tastiest bits. Miss Manners has no objection to your dislodging the clinging froth, so long as no inadvertent spectators are injured.

DEAR MISS MANNERS: Sometimes, when at a loss as to what to get someone, I opt for a gift card. A while later, I have pleasantly asked what they got with it.

Oh my goodness, you'd think I'd rudely asked them if they were wearing any underwear! And they won't say or can't remember. Not just one time, but every time -- the teenagers are the worst.

So I adapted, and at the giving time I have sweetly asked (with brief eye contact) to please let me know what I "got" them.

Oh yes, they certainly will. Happiness and smiles all around. But then they don't. Is it wrong to ask what someone got with their gift card? My current solution has been to tell them I will be giving them a gift card and ask where would they would like to use it.

GENTLE READER: The reason Miss Manners dislikes gift cards is that they show a lack of knowledge or effort -- or both -- on the part of the gift giver.

So it does not seem fair that, having not yourself made the effort to determine what the recipient would like, you should also burden them with having to report back the results. The simplest way to know what you give people is to give it to them.

DEAR MISS MANNERS: When friends invite me over for dinner, sometimes the meat they have lovingly prepared is served with large amounts of fat. I have always trimmed it off and set it neatly to one side as I would bones, and no one has ever said anything.

Still, I have begun to worry that this may imply a criticism of their meal. I have been unable to determine if they eat or don't eat it.

GENTLE READER: Presumably it is easy enough to see if your hosts eat the fat on their own plates, and Miss Manners does not inquire what happens to food on your plate after it is removed from the table. If the dog is enjoying the bones, she has no objection.

You are entitled to eat -- or not eat -- what you wish, so long as you do not attempt to explain it. And if no one is complaining, your concern appears to be unwarranted.

DEAR MISS MANNERS: My brother-in-law corrects me when I don't say "please" to my husband. What I say is, "Will you get me some coffee?" That is asking, not demanding.

I am 62, and my brother-in-law is 60. This is crazy!

GENTLE READER: Crazy, in Miss Manners' opinion, is eschewing polite forms with someone with whom one lives. And, for that matter, attempting to teach manners to one's stubborn sister-in-law.

DEAR MISS MANNERS: I received a postcard announcing the upcoming birth of a baby, four months into the future. The card was similar to a "save the date" for a wedding.

Having never received one of these cards, I'm unsure how I'm to respond or if I need to. Am I to send more than congratulations? Am I to send a gift? Is this the newest trend in "save the date" cards?

GENTLE READER: Let us hope not. What exactly would you be saving the date to do? Congratulate the parents, and then listen to them burst into tears because the time was up and nothing had yet happened?

It strikes Miss Manners that these prospective parents are amazingly ignorant of the ways of babies. They are in for a shock when they discover that babies have their own agendas.

And even if they have scheduled an inducement, it would hardly be the day they would want to field calls and texts. Despite the ridiculous card, the tactful thing for you to do would be nothing whatever until you receive a birth announcement.

DEAR MISS MANNERS: My brother just canceled his wedding less than three weeks prior to the event.

As we begin to discuss dealing with the aftermath, I wonder what the proper way of notifying guests would be. Does this type of thing necessitate a phone call or would emails suffice?

How much information does one divulge? If, as I suspect, this type of thing requires a phone call, can a family member help make said calls? How does one best respond to the inevitable question of "Why?"

GENTLE READER: There is a formal, third-person form for such an announcement ("Mr. and Mrs. Parents/announce that the marriage of their daughter/Olivia Zoe/to Mr. Humphrey Joshua Whittleby/will not take place"), but three weeks is a short time for people to cancel their travel plans and stop fussing about what to wear.

So yes, in this case the family should use instant devices to get in immediate touch with those invited to the wedding. Whether that would be by telephone or by email should depend on how you can be sure of reaching them, considering that some people no longer answer calls and others are not in the habit of checking email.

The explanation for all should be the same: that the couple canceled the wedding by mutual consent.

Miss Manners realizes that this will satisfy nobody, but it should be the only statement repeated to those who keep asking. There will be enough gossip about the situation without the family's adding to it, and your brother will have to decide how much he wants to explain to whom.

DEAR MISS MANNERS: I am wondering if it is polite to have a birthday dinner where the guests don't know each other. My friend had a dinner party of 10 guests where the guests didn't know each other.

GENTLE READER: Didn't they, by the end of the evening?

One of the pleasures of hospitality is putting together new combinations of people who might enjoy one another's company. Of course, Miss Manners is presuming that they have something in common: that they all know the host.

DEAR MISS MANNERS: In a small movie theater, at the end of the show, the couple sitting two seats away from me asked if I had enjoyed the movie.

I smiled and said very much so, and they proceeded to tell me in front of others that I had completely ruined it for them because of my noisy popcorn chewing, and they hadn't been able to hear a thing. I apologized and said they should have told me sooner.

I was horribly mortified and upset, and when I ran into them in the lobby on the way out, I explained that I am the sole caregiver for my disabled husband and am able to get to a movie twice a year at best, and if it was any consolation for them, they had also now completely ruined the experience for me.

I again said they should have said something sooner and walked away before giving them a chance to reply.

Is there any way this could have been handled better by either party? I also don't believe I chew popcorn any louder than anyone else and have certainly never been told so before.

GENTLE READER: Well, Miss Manners is not in a position to weigh in on that. She does agree, however, that if the offending noises were such that the couple could not enjoy the movie, they should have said something at the onset. Something such as, "Excuse me, the popcorn seems to be unusually crunchy, and our seats are so close together. I wonder if you would mind chewing a little more quietly."

Miss Manners cannot guarantee that you would have been any less taken aback by the request, but at least it would have been made politely.

DEAR MISS MANNERS: At a friend's wedding reception, bottles of wine were placed on guests' tables for consumption during dinner. The reception was a simple and elegant affair that concluded shortly after dinner.

My husband and I were seated with two other couples, including a good friend and her husband. Upon leaving, my friend's husband took several bottles of unopened wine from other tables, hiding them under his jacket.

I told him, in front of the others at our table, that I didn't believe that the wine was intended for "take-home" and that he should put them back. He shrugged and ignored me.

I admit that I was rude, but how else should I have handled this? Looked the other way when someone was stealing? Regretfully, this all got back to the bride, who told me to let it go, and that if he was that desperate for a few bottles of wine, so be it. I feel as though I have caused unnecessary strife. What to do now?

GENTLE READER: Apparently you resisted crying out "Stop, thief!" and sounded as if you were merely calling attention to a misunderstanding on his part. So Miss Manners does not think you need to apologize.

But now, having made your point, you would do best to, as the bride and every child under 10 says, "Let it go."
