DEAR MISS MANNERS: What is the proper etiquette regarding tours of your house to visitors who have never been there?

For close family members and friends, it seems obvious. But more casual guests for a dinner party or the like pose a quandary. "Would you like to see the rest of the house?" seems an obvious assumption that you will get a "yes." For some reason, it seems rude not to offer, and doing so seems like an attempt to elicit compliments.

For the record, our house is not spectacular; nobody's going to be giving tours of it when we're dead. If someone doesn't ask to see the "rest of the house" should I just let it go?

GENTLE READER: Where did you get the idea that a house tour is mandatory for all guests, on request or without? Miss Manners can think of many reasons why it is a bad idea:

It smacks of showing off.

It uproots people from sitting comfortably and makes them march around, trying not to slosh their drinks on your bedspread.

It invites nosiness and pushes even polite people to comment on your style of living -- charmingly to you, but perhaps more freely to others later.

No doubt you have exquisite taste, and you may want to show your intimate friends and relatives your new house. If you lived in Monticello, you could consider yourself obliged to allow the public limited access. But to open it to everyone is to invite judgment.

The old rule against commenting on other people's possessions has been unfortunately overwhelmed by the era of posting in the hope of "likes." And you may have noticed that those who are posting don't always like what that brings in.

DEAR MISS MANNERS: I always write thank-you notes, though I rarely receive them. The act of gratitude is something that I enjoy and that brings me joy.

However, I've occasionally been chided because I prefer to write in pencil. I might make spelling or grammar mistakes, and I like to be able to correct them without making ugly marks scratching it out in pen. Is it rude to write a thank-you note in pencil? What about other casual notes/letters?

GENTLE READER: Allow Miss Manners to introduce you to a wonderful modern invention: tiny rolls of tape or bottles of liquid that whitewash mistakes made in ink.

Your correspondents should not be criticizing your letters for whatever reason, but perhaps it is because they treasure them and want to make sure that they will be able to re-read them in future years.

DEAR MISS MANNERS: What are the rules on tipping a proprietor of a business?

When I was served by the owner of a restaurant, I asked him what was the rule on his accepting tips (I had heard that you are not expected to tip the owner). Everyone I was with was very surprised and said you always tip for service. The owner said he gives all of his tips to his other staff.

GENTLE READER: The rule is that the owners are not tipped, and many owners are doing everything they can to repeal it.

But Miss Manners notes that this particular owner has tactfully acknowledged that without discouraging you from making a contribution. Having asked, you were obliged to do so.

DEAR MISS MANNERS: My brother told me that he disapproved of my intention to give my teenaged niece a small makeup kit as a gift. He said I should have asked his permission first.

I know my niece is allowed to wear makeup, as I have seen her do so at family functions. While I support his right to determine what is appropriate for his daughter, I feel the line should be drawn well short of dictating gift choices. Gift-giving is supposed to be an expression of regard from the giver to the recipient, is it not?

I took the time and thoughtfulness to choose a gift I thought my niece would enjoy. I ended up returning it in favor of a gift card to a big box store, since I didn't see how my brother could object to that, but all the joy of giving the gift is gone.

GENTLE READER: Indeed. What fun is there in being the favorite aunt or grandparent if you can't annoy the parents with presents that undo their rules and parenting in the process?

Miss Manners agrees that barring any truly bad taste or danger, presents should be up to the giver. It is then the parent's privilege to withhold their use until the recipient is "living in her own house and paying her own rent."

DEAR MISS MANNERS: I'm in my early 60s and have found myself working in a department with co-workers who are all in the 25-to-35 age range.

They are all smart and pleasant (some more than others), but in their daily back-and-forth banter they constantly make fun of older people. Life is not worth living once you hit 30, older people shouldn't be taking zumba classes, are terrible with technology, are boring, shouldn't have their pictures on the corporate website because they look so ... well ... old! -- that sort of thing.

I don't believe they're saying it to hurt my feelings; I just think they forget that I'm there. I work very hard to go above and beyond in the job, but I seldom show up at happy hours or participate in long conversations about the Kardashians and the best place to get a taco.

I may have made a few jokes of my own at their age, but I don't believe I was ever so consistently insensitive. I'm actually horrified that their parents are my contemporaries and raised them to be rude and immature, and terrified of getting older themselves.

I realize this is "ageism," but it doesn't bother me enough to approach Human Resources. In the end, I believe that would cause more problems than it solves.

I'm at a loss for a witty comment that would gently point out that they are idiots. Can you suggest one, or would the attempt be simply ineffective?

GENTLE READER: Perhaps during these unpleasant sessions, you could helpfully remind them that you are there by continually saying, "What?" and asking them to repeat themselves. A lot.

If done with humor, Miss Manners hopes that even the most immature will surely get that you are demonstrating -- and they are perpetuating -- a silly stereotype. At minimum, the point will be made that they should keep their ridiculous and shortsighted opinions to themselves -- or at least out of earshot.

DEAR MISS MANNERS: What is the best way to reply to a text that says just "Call me"?

I find it unspeakably rude and peremptory. If someone needs a call with me, they can call! If they don't want to call at a bad time, they could text "May I call you?" or "When is a good time to talk?"

But summoning me to call them is offensive. I generally ignore these texts rather than responding with what I'm thinking. Or I reply with a time to call me. But people really don't get the message. What's a good reply that lets people know this is rude?

GENTLE READER: "All right, I will."

DEAR MISS MANNERS: A friend invited me to meet him on his lunch hour, and when I arrived at the casual food shop, he told me that he was fasting and would not be eating anything.

I said that was rude. He said he just wanted to spend time with me. I ate alone while we chatted. Should he have told me in advance that he wouldn't be sharing lunch with me?

GENTLE READER: The key word here is "hour," not "lunch." Presumably this was the time that your friend had available -- and Miss Manners fails to see the affront in his wanting to spend it with you. Had you not scolded him, you might have noticed that the fact that both of you did not have sandwich drippings hanging from your mouths likely made the conversation better, not worse.

DEAR MISS MANNERS: I am recently widowed, and I understand friends and family have genuine concern for me. In addition to the normal loss, there are circumstances surrounding my husband's death that disturb me, but I don't want to share with anyone other than legal counsel.

I'm trying to be gracious when people inquire about my well-being, but I'm getting fed up with "But how are YOU doing?" I'm not doing well and would prefer not to talk about it in public or private, thank you.

Everyone needs to know that this is a nosy question that is inappropriate. Ask if there is anything you can help with, or if you can meet me for lunch. Ask, "Can I take anything to charity for you? Run errands? Address thank-you notes? Take the car in for maintenance?"

Asking HOW I am doing brings up sad topics such as: My income has been cut in half, the lawyer cost three times what I thought it would, I don't want a funeral but everyone else does, his wishes and mine were ignored by health providers who thought I would never find out (hint: medicine sends a record of any procedure to the patient's home). That's all too painful to talk about. There's merit in not bringing this up.

GENTLE READER: And yet here we are. While emphasizing different words within the otherwise innocuous question "How are you doing?" may appear to make it loaded or cloying, Miss Manners begs you to try not to hear it that way. People are floundering and trying to think of something to say when they really just want to help. So think of it instead as an invitation to talk about whatever you wish, be it car maintenance, lunch plans or medical fraud.
