DEAR MISS MANNERS: I am curious to find out what would be the most acceptable and polite answer in this situation: A man (stranger) feels that a woman's dress is indecent and comes up to this woman inside a venue to tell her directly that she needs a change of clothes because she's not appropriately dressed for the event.

Since they haven't met before, how should she respond to such a brash and confrontational statement?

GENTLE READER: If you intend to be the critic in this situation, Miss Manners can assure you that the response will not be one of gratitude or contrition. It may even require a towel if the lady in question is holding a full glass. She urges you to rethink your plans.

If you are, instead, what can reasonably be termed the victim, she asks only for restraint -- while acknowledging that the behavior is a gross insult, which does not require a nuanced response. After a cold "Thank you for your opinion," the lady should walk away. What a woman who is not a lady might do, Miss Manners does not know.

DEAR MISS MANNERS: Two days after my town lost three teenagers to a tragic car accident, a community member began selling memorial T-shirts that were donated by a local family in the T-shirt business. All proceeds are to be given to the families to help with final expenses.

On the front of the T-shirt is an "inspirational" message, and the back has the names of the three children with their birth dates and the date of the accident.

I think their hearts are in the right places but, to me, it seems to trivialize and cheapen the memories of these children.

When I suggested that perhaps donations should be sought in order to provide a more lasting tribute than a T-shirt, I was accused of "starting drama." I was trying to think of how I would feel as a mother if next year someone is washing his car with that T-shirt or dropping it off to charity.

I suggested that a tree planting with a small plaque or a small monument at the school the three children attended would be more lasting, and was surprised by the nasty responses I received for not supporting the T-shirt sale.

Miss Manners, I don't want to further hurt an already grieving community, but am I wrong in thinking that a "T-shirt memorial" is cheap and tasteless?

GENTLE READER: No good comes of a competition over whose memorial is the most fitting or whose flower arrangement is the best. Funeral etiquette recognizes a hierarchy of grief, and while your community may be grieving for the loss, Miss Manners reminds you that it is the feelings of the principal mourners -- the immediate families -- that take precedence. How would you, as a mother, feel watching others argue over the tastefulness -- or tastelessness -- of the arrangements?

DEAR MISS MANNERS: Please advise me on the proper way to eat spaghetti when a family of little kids and adults are informally around the dinner table.

Next, what's correct for a gathering of only adults? And finally, how should it all be done when there is a major formal place setting for each guest?

If they wish, others may go ahead and sing "Jam your right fork in, pull the oozy gooey out, twirl it high into the air, and catch it in your mouth" -- the "meatball on the floor and out the door" song. I only want to set a proper example.

GENTLE READER: That is noble of you, but Miss Manners pictures your relatives' pasta getting cold while they ponder what age qualifies as adulthood, or what degree of formality requires which approach.

You are in dire need of a unified spaghetti policy. And please stop tempting chaos with jingles.

The correct method does not involve a spoon. It is necessary to state that, because Americans of Italian descent often argue that it does. Bracing the tines of the fork against a spoon is considered rather crude (although not as crude as your song) in Italy.

Rather, the fork should be planted, tines down, against the plate, and rotated so that the spaghetti is wound around it. Those pesky strands that refuse to wind can be cut with the side of the fork.

DEAR MISS MANNERS: I have to meet with people in a social setting occasionally that is not of my choosing; they don't like me and I don't like them.

If I don't offer my hand for a handshake and they offer theirs, is it proper to just say hello and ignore the proffered hand?

I'm sure their feelings won't be hurt, but don't really care if they are, and I get resentful at myself for being a fake or phony for shaking hands with people that I don't like.

GENTLE READER: Refusing to shake someone's extended hand without offering an apologetic excuse (such as a medical problem or religious prohibition) is a severe insult.

But then, that is what Miss Manners understands that you hope to deliver. You just don't want to accept the consequences of delivering a public slight that might provoke retaliation from the victims.

Perhaps you are right that some people will not understand the insult, or will be generous enough to assume that you don't understand having given one. That does not make the prospect of your chortling to yourself any less unpleasant. And it runs the risk of a scene that would embarrass your hosts. At most, Miss Manners will allow you to get away with a slight coolness.

DEAR MISS MANNERS: How to respond to a young man when he asks to marry your daughter? It is a yes answer.

GENTLE READER: Well, then, say yes.

Traditionally, this is the occasion to grill the prospect on his ability to support your daughter in the manner in which she is, or hopes to become, accustomed. However, Miss Manners must warn you that nowadays this could lead to an even less pleasant session with your daughter.

DEAR MISS MANNERS: I was introduced to a young dandy about my age who had worn his feathered fedora during a church wedding and was now wearing it at the reception.

Presumably I was expected to concur with his being introduced as "the most dapperest man I know" and to immediately compliment his attire.

Do you have a better retort than the one I used: "Gosh, you are so well-dressed. Foolish me, failing to protect my eyes from the blinding rays of that chandelier."

GENTLE READER: "Most dapperest"? A man wearing a hat indoors seems to Miss Manners to be the most rudest. There was no need for you to comment at all. Just a weak smile and innocuous comment about the wedding would have sufficed -- until you were able to make a polite getaway.

DEAR MISS MANNERS: My husband and I attended the opening performance of a major orchestra. We had excellent seats (the second box in the first balcony) and were seated with five other couples that we did not know.

Three of those five couples spoke multiple times during the orchestra's performance of Mahler's Second Symphony. I was at a loss about what to do. Whispering during movies is so common now that I know that I've lost that battle, but I'm not ready to give up the fight at a performance of one of the finest orchestras in the world.

Would it be appropriate to make a general statement to our box before the performance begins? I'm thinking of something like this: "I'm sure nobody in this box would think of it, but let's all agree not to whisper to our companions during the performance."

Or would it be more appropriate to wait for the intermission and speak directly to anyone who has spoken during the first piece?

GENTLE READER: The best defense is a good offense (look at Miss Manners getting all sporty), but that said, the approach you're considering is just slightly condescending and prissy. Those with rebellious leanings might want to defy you just for the fun of it.

Instead, you might tell a cautionary tale of the aforementioned event in which people were so brazen as to speak during the performance (presuming the current attendants were not among them). This will make your point without directly implicating your new companions.

DEAR MISS MANNERS? Do you think that wearing sunglasses and/or a headset when you visit friends at their home is appropriate? Walking down the street, is it appropriate to wear your headset while listening to music or answering the phone?

My friend thinks it's OK because that's the way he was brought up. When I tried to explain to him that it's rude, he got upset at me.

GENTLE READER: Goodness knows that the way one was brought up isn't an excuse for rude behavior. It is often, as in this case, the culprit.

Wearing a headset or sunglasses while in someone's home is impolite (unless the latter is for medical reasons). Walking down the street with them is not, although Miss Manners warns against playing music so loudly that you can't hear oncoming traffic -- or your friends giving you misinformation.
