DEAR MISS MANNERS: Is it appropriate for the Nobel Committee to call prize winners at all hours of the night in order to inform them of their award?

I understand that the Nobel Prize is very important, but it seems to me that it does not qualify as an emergency, and I assume that prize winners are busy people who may be expected to give lectures the next morning.

Also, I think that the Nobel Committee can be expected to be aware of time zone differences.

GENTLE READER: Probably the Nobel Committee can figure out the time difference. But Miss Manners warns you that you are suggesting that they deprive themselves of half the fun in giving out the prizes.

The routine is that some physicist or chemist who leads a quiet academic life is startled awake by the telephone, only to assume that a merry colleague or cheeky student has pried into his or her dreams and is ridiculing those secret fantasies.

"You can't fool me," says the winner crossly. "That fake accent of yours is terrible."

"What is it, dear?" asks the sleepy spouse.

"It's a hoax."

"How do you know?"

Meanwhile, the Nobel Committee representative, who has been through all this before, is hugely enjoying the situation while reassuring the winner that the dream has really come true.

As for the next morning's lecture, you needn't worry. Everyone in the lab will be swilling champagne, and no lectures will be given that day.

DEAR MISS MANNERS: When my girlfriend and I were walking into the supermarket, a man walking in the other direction (leaving) said hello to my girlfriend as he came abreast of her. He didn't say hello to us as a couple, but only to her.

She returned the hello, and continued walking with me into the supermarket.

I think it's inappropriate for a woman to reply. I think if a woman is walking with her man, she should ignore another man's hello, because she is in my company and it is disrespectful to do so.

What are your thoughts on this matter? Am I being too sensitive, or was it disrespectful for her to reply?

GENTLE READER: Too sensitive? To the lady's feelings, or to those of her acquaintance whom you want her to snub?

And for that matter, what about some respect for Miss Manners and the noble discipline she represents? Did you think she would encourage your lack of respect for these people, and supply ammunition with which you could further insult the lady while claiming respect for yourself?

DEAR MISS MANNERS: I gave a dinner party where one person was a smoker while the remaining guests were not. The smoker excused himself to go outside to smoke during the meal.

Should I, as hostess, accompany him, leaving my husband to entertain the remaining guests? Or should we leave the smoker to his own devices?

GENTLE READER: Do you smoke? And if so, are you so heavily addicted that you feel you have to disrupt a dinner party in order to indulge?

Such is the unfortunate plight of your absent guest. Why you would consider imitating him, Miss Manners cannot imagine.

DEAR MISS MANNERS: When arriving at someone's door, how many times should you knock?

GENTLE READER: It is considered courteous to stop knocking as someone's face appears at the door.

DEAR MISS MANNERS: At a very high-end restaurant, my fiance and I, who had a reservation, were seated far in the back near the desk where waiters run checks.

I asked the hostess if we could sit somewhere else. She said there was nothing available, but that we were welcome to wait at the bar until a new table opened up.

I said OK, and we waited for about 10 minutes at the bar until we were able to be seated somewhere much nicer.

I found out later that my fiance was mortified that I had even asked. Was this rude? I felt that if we were going to spend a large amount of money, I would like to be seated somewhere comfortable. I did not cause a scene or demand to be seated immediately.

GENTLE READER: Presuming that the food agreed with you, you have nothing to feel bad about.

If you are paying for a service, you should ask politely that it be to your liking, and this was a reasonable request that the staff could easily accommodate. A good restaurateur would prefer to accommodate you than to let you go away in dissatisfied silence. Besides, you probably ran up a nice bar tab while you were waiting.

If the hostess showed no objection, then Miss Manners assures you that your fiance should not either. Perhaps he should save his mortification for any untoward dinner conversation.

DEAR MISS MANNERS: I was invited to lunch by someone I did not really know, and during the luncheon, I realized that I had little in common with the person, and in fact did not like them much.

But I grew up with the understanding that if someone invites you to a social event, you are then obligated to reciprocate and invite that person to a similar occasion.

If this is still protocol, what does a person do when s/he finds out that they do not actually like the person who first invited them? Hosting a social event is not inexpensive, and I am on a limited budget.

Are there other options? Of course I mailed a formal handwritten thank-you after the affair; I also contributed a dish to the meal.

GENTLE READER: While it is generally polite to reciprocate social events, doing it precisely in kind is not necessary (it is only when the entertaining becomes completely one-sided that Miss Manners objects). It is not required if you do not enjoy the person's company, and your host may be equally relieved to bring the acquaintance to a graceful end.

A handwritten thank-you is enough. Any social repercussions -- not being issued further invitations by this person -- will, in this case, accomplish the desired result. Besides, by providing food, you fulfilled a hostly function yourself.

DEAR MISS MANNERS: I sent out an electronic invitation for a casual dinner party. To my horror, Evite the invitation site added a link (it was an advertisement attached to the invitation) to be clicked, saying "Send a gift immediately."

I can understand (although not approve of) gift information for something like a child's birthday party, but I am mortified that my guests thought I was panhandling for gifts. I had to send out a second email saying "No gifts, please."

Is there something more I should do to make amends for this?

GENTLE READER: The website you used has put you in an embarrassing position, but fortunately you owe the company no loyalty. Your situation would be trickier if your brother's girlfriend had somehow added to an invitation of yours without your knowledge.

Miss Manners suggests an email to your guests expressing your surprise and dismay at the company's greedy link and explicitly disowning its action. She would also have you share your frustration with the company itself, explaining that it embarrassed you. Whether you want to reciprocate the embarrassment by exposing it on social media is up to you.

Although Miss Manners has little hope that an internet company will opt for good manners over profit, perhaps it could provide the host with a optional "request loot" checkbox, thus permitting clients a choice of whether or not to be rude.

DEAR MISS MANNERS: I make a great many handmade gifts -- some simple, small items, some grand gestures to commemorate graduations, weddings and other special occasions.

My problem is when years later, 15 to 20 years even, people say something along the lines of, "Oh, I love the little embroidery bag you made me. I still get wonderful compliments on it, and many people have asked me about it."

About 75 percent of the time, I have no memory of what I made them or why. I usually respond with a smile, a thank you, and something such as, "I am so happy you enjoy it."

It is true that I am happy to have brought joy into someone's life. Most people are fine with that, but others probe a bit further, and it's quite evident that I have no memory of what I made them.

I feel bad about this, but they are often offended if I tell them I am sorry I don't remember the item clearly. Is there a better response? I feel as if I'm violating some rule of etiquette that says I need to remember every gift I've ever given.

GENTLE READER: It seems ungrateful for a gift recipient to be annoyed that the sender does not remember the gift 20 years later. What is important is, as you say, that the recipient enjoyed it.

It is also, Miss Manners notes, unfair, since the recipient has the gift in hand as an aide memoire. The person who does not accept your apology graciously is the one being rude, but in the interest of harmony, you could say, charmingly, that perhaps your memory is not what it once was. And indeed, you should endeavor to forget these entire encounters.
