DEAR MISS MANNERS: I hosted a family party, and after lunch, my daughter, granddaughter and myself were laughing, joking and cutting up. Just having fun. My family tends to get loud, I confess.

My sister, brother and husband were in an adjoining room, and suddenly my sister turned toward us and said, in a loud and very gruff voice, “Y’all have got to quiet down in there! We can’t carry on a conversation in here.”

I apologized and took our conversation into another room. My granddaughter later drew attention to the fact that my sister should not have yelled at my guests in my home; I agreed.

Whenever I try to talk to my sister about it, she deflects from the issue and says we were the ones being rude. I have explained to her that we weren’t trying to be rude, we were just being ourselves. And that as soon as I became aware of the problem, I took care of it. Until she yelled at us, I was not aware that she was becoming irritated.

My stance is that no one should yell at guests in another person’s home. (I would never do that to her.) And that she should have come to me and let me know she had a problem, giving me a chance to handle the situation.

So, Miss Manners, who was rude? My sister, or my guests and me?

GENTLE READER: Your sister. However, Miss Manners cautions you not to use “being oneself” as an explanation for rudeness, however incorrectly it was perceived. The important difference here is that once you were made aware of the annoyance, you stopped. Perhaps your sister will now be able to follow suit.

DEAR MISS MANNERS: I went to a restaurant with an elderly friend who was using a cane and had recently had a stroke. There was a waiting list to be seated.

The entryway had two benches, both of which were filled with 20-something couples and their young children. Some of the children were approximately 5 years old and lounging between their parents as they used up every inch of the seating. No one offered my elderly friend a seat.

I thought about saying something to the parents, or asking the 5-year-old boy, “Would you like to learn how to be a gentleman?” but decided not to say anything to him or his parents. I felt there was no way, no matter how gently I phrased it, to address this without causing problems. How should I have handled this?

GENTLE READER: While these families certainly appeared to be rude and inconsiderate, Miss Manners thinks it more likely that they were just oblivious. Probably the parents were just grateful that their children were not actively causing a public scene and did not even notice your friend.

Assuming this, you could reasonably address a family directly without it sounding harsh: “I wonder if you might make some room for my friend to sit down. He has trouble standing.”

DEAR MISS MANNERS: My husband and I got a Facebook invitation to attend my sister-in-law’s wedding rehearsal dinner. Since our children are in the wedding, we RSVP’d that four would be attending. Under the menu was “$30.”

I had never heard of a wedding party being asked to pay for their own rehearsal dinner. When I asked about it, she was furious: “Of course you are paying for your own meal! You really need to check wedding etiquette. We’re not going to pay for everything!”

Honestly, I thought I knew wedding etiquette. But I frantically searched the internet. I was hoping to smooth things over by letting her know that I was now up-to-date on my wedding etiquette, hadn’t realized what I was asking was in poor taste, and that I was just trying to budget. The best I could find was something called a “no host” party.

We had budgeted buying the kids’ clothes for the wedding, and for a gift. I don’t think it would be polite to skip the rehearsal, so now we’re also paying $120 for one meal. My husband says we should only give them a card, since we are paying for the dinner.

I’m left with two questions:

1. Is it new etiquette to ask a bridal party to “BYOD” -- buy your own dinner?

2. Is my husband right in suggesting that we shouldn’t give her the monetary gift, since we are spending it on the rehearsal dinner?

GENTLE READER: So many etiquette rules are being violated here that Miss Manners hardly knows where to start. Suffice it to say, using the internet to validate rudeness disguised as etiquette is confirmation bias at best. She is relieved that you came to your senses and consulted her instead.

To answer your questions:

1. No. It was invented to allow people who want to have a party thrown for themselves to make others pay for it. As you point out, it is not only rude, but it adds to the already considerable burden of the guests. Always beware of acronyms that require large purchases.

2. Yes and no. A wedding present should not be monetary in the first place -- another incorrect assumption created for personal gain. Presents are always voluntary. However, if you choose not to give one for your husband’s reasons, you would be validating yet another made-up rule: that the price of the dinner should be the amount spent on a present. Only in this case, you are doing it in reverse.

Your best recourse would be to give a small, token gift that you think the couple might like. And not to consult the internet.

DEAR MISS MANNERS: My daughter just moved into a newly developed neighborhood. Her neighbor, who moved into her new home only a few weeks prior, gave my daughter a housewarming gift. Should my daughter reciprocate with a gift, or just with a thank-you note?

GENTLE READER: Chronology takes precedence with housewarming, and since your daughter was the last one to move in, she is the more logical choice for the present. A thank-you note from her is sufficient, but a neighborly treat to accompany it, or an invitation to the house to visit, would be charming. As would, Miss Manners feels compelled to add, paying the gesture forward for the next new neighbor.

DEAR MISS MANNERS: A female friend and I went out nightclubbing one evening several weeks ago, and I drove. In the past, we have normally left to go home around 11:30 p.m. At 11:30, I told her I was ready to go.

She informed me (after four to five glasses of wine) that she was not ready to leave. I told her I was serious and wanted to go home. She repeated that she was not ready.

Next, I told her that I was going to the car and would meet her there, hopefully very soon. Thirty minutes later, I was still waiting for her in my car. I went inside and told her that I would be leaving, and that if she wanted a ride, to please follow me to the car, and that I was very angry.

She came to the car, but started in on me, suggesting I was not acting rationally and was being unreasonable and so on. She told me that the decision to go home should be a joint decision. I basically told her she was lucky I had not left her there and driven home.

This friend of four years has not contacted me or apologized. I think I was more than nice and no longer consider this woman my friend.

GENTLE READER: Your offer of a ride -- and your friend’s acceptance of it -- bound you both, in differing ways, as companions for the evening. She owed you the duty of a guest to be grateful and accommodating; you owed her the duty of a hostess to show an interest in her comfort -- and also to see her safely home.

This required compromise seems to have been lacking on both sides. But while the obligations may have begun the evening as more or less equal, they began to lean more heavily in your direction as your friend’s ability to stand up straight became compromised.

Assuming your friend was not wholly incapable of independent action after four or five glasses of wine, it would have been enough for you to ensure that she had an alternate way home, either by checking that she had cab fare or by asking around for an alternate chauffeur. This would, Miss Manners notes, have discharged your own obligations without either inconveniencing you or losing you a friend.

DEAR MISS MANNERS: How do you serve yourself a piece of hot bread from a shared basket when the bread needs to be pulled apart? It always comes without anything to use but your own hands.

GENTLE READER: There is a reason sliced bread is cited as one of civilization’s great inventions.

Absent a bread knife, the alternatives range from the impractical -- a table knife is more likely to harm the wielder than the bread -- to the unsanitary -- Miss Manners presumes that wolves do not mind other wolves using their teeth, but people decidedly do.

That leaves looking around sheepishly to see who is watching and then wrenching off a piece as gracefully -- and quickly -- as possible. There is no prohibition against requesting a suitable knife, particularly in a restaurant. In a private home, you may wish to skip the bread, and later add a bread knife to your gift list for when the host’s birthday comes around.
