DEAR MISS MANNERS: What is the proper etiquette for disembarking a plane when the aisles are full and someone's bag is several rows behind them?

I was getting off a flight when a couple in the row in front of me tried to get other passengers to retrieve their large carry-on bags from the overhead compartments, four rows back, and pass them up to them. When that didn’t happen, the man pushed back through those of us standing in the aisle.

When I suggested he wait a minute or two and we’d be cleared out of his way, he very loudly told me that I didn’t know disembarking etiquette and that everyone behind him should have waited for him to get his bag.

It would be helpful to have your input for our collective travel in the crowded skies.

GENTLE READER: Public chastisement in the name of etiquette is Miss Manners’ least favorite form of free advertising.

This person’s method was not even logical, because other passengers could hardly be expected to know where his bag was and at what point to stop passing it.

Had he been more courteous, others might have taken pity on him and asked if they could help. As it was, he made a challenging situation worse -- and turned his fellow travelers from potential allies to adversaries.

DEAR MISS MANNERS: I refused to attend the wedding of one of the teachers at my wife’s dance studio when the invitation included their bank account info, asking for "cash gifts ONLY." The wedding was at a remote location, with the closest hotel 45 minutes away, in the middle of the forest with no illumination down some unpaved roads.

My wife attended and deposited the cash gift. Was I wrong?

GENTLE READER: Yes. But only because you abandoned your wife in the middle of a forest.

DEAR MISS MANNERS: My husband and I spent a few days with some friends at a house in a rural setting near a small lake. During our stay, the electricity went out.

The toilets did not work for over 24 hours, and we had to use buckets for the waste we generated. After the toilets were working, our host disposed of our collected waste in the lake. Doing so was against the law in the state we were in. It was also an ecological crime because even an infinitesimal amount of feces will pollute a lake.

We said nothing at the time. When a host commits both a crime and causes an ecological disaster, what is a guest supposed to do? Should we have stopped our host? Should we have said something?

GENTLE READER: It is not an unreasonable expectation that the owner of a house be familiar with the laws and idiosyncrasies of its state. Deferring to your hosts and their expertise is indeed logical and polite.

But if you know that a crime is being committed, speaking up is imperative. Because even Miss Manners will admit that etiquette is not above the law. If your friend gets caught and you are named as an accessory, “I was just being polite” will probably not serve to exonerate you.

DEAR MISS MANNERS: A friend from college works in Europe now and asked to stay with me for 10 days when he was here visiting. I made sure he had fresh towels every day.

His first day here, he flooded my bathroom floor while taking a shower (he said he "forgot how shower curtains work") and called for help. I quickly grabbed a towel and threw it down to wipe up the water before it seeped onto the hardwood outside the room. I immediately put the towel into the washing machine.

He was appalled, and said I should have grabbed a mop instead of putting a towel on the floor.

It’s not like it’s a bus station bathroom -- I don’t have kids or pets, I don’t wear shoes in the house and the floor is always clean.

After that, he said he couldn’t trust my towels. He went out and bought his own towel to use and kept it with his things until he left. I offered to wash it so he wasn’t using the same towel for days, but he refused.

Am I really that disgusting?

GENTLE READER: Why are you accepting criticism from someone who cannot figure out a shower curtain? And who made the mess in question in the first place?

Regardless of your towel hygiene, Miss Manners finds this person’s attitude appalling. To chastise you for attending to his mistake and then act as though your laundry were now tainted is rude and hypocritical. He is the one who should be apologizing, not you.

That said, Miss Manners’ personal preference would be to use a mop or non-guest towels to clean the floor. But as a guest in your house, she would never have said it.

DEAR MISS MANNERS: My oldest child is about to turn 4, and we plan to invite other local children to celebrate. We live in a very small town where the custom seems to be to invite the entire preschool (around 20 kids). After talking with another preschool mom, my husband and I have decided to rent a local event space to host the party. This will allow us to invite all of the kids without worrying about having room.

Because of the extra space, I would like to indicate on the invitations that parents may bring their older and younger children if they wish. We would also like at least one adult from each family to plan to stay at the party. This is important for us because we do not know most of these children or their parents.

I do not wish to be rude and am struggling with the wording for the invitations. Is this too blunt? “Older and younger children are welcome, and we invite parents to stay. Please let us know how many plan to attend.”

GENTLE READER: Perhaps “Siblings and parents welcome” is a little more succinct, but asking how many will attend is fine.

Miss Manners will warn you, however, that blunt does not always yield a response. And that you may well have opened the floodgates for guests to bring anyone they want -- now and for the life of your children’s birthday parties.

DEAR MISS MANNERS: My husband and I are frequently invited to another couple’s parties. We are all gay, male seniors.

One member of this couple seems to be going through some cognitive issues. He tells everyone assembled the same lengthy jokes and goes on and on about his religious and political views, always offending some present.

We have run out of excuses to skip these parties, and sometimes just attend for an hour or two, mostly out of compassion for his husband. He presents a lovely buffet and must be struggling with his husband’s challenges. We bring a gift on the few times we attend.

We don’t want to tell the husband why we would rather not attend future parties for fear of being cruel. My husband and I are disabled and not able to entertain. Even if we could, having them over would end up driving us to distraction, divorce or worse.

Do you have any ideas on a better way to handle all of this? Are we boors for not reciprocating?

GENTLE READER: Someone evidently told you it would be a virtue to be honest with your hosts about why you dread their parties, but it was not Miss Manners. She is relieved that you have not done so.

It would not only be cruel, it would be rude and self-serving -- assuming it was meant to justify your feeling good about staying home. Spelling out the issue would also be pointless, as the unimpaired spouse is only too aware of the impact his partner’s behavior is having on their social life.

The virtue is in what you are doing: namely, putting up with as much of the behavior as you can, because you feel for one spouse and believe the behavior of the other is beyond his control.

DEAR MISS MANNERS: My fiance and I moved to a new neighborhood, and our neighbors have been really friendly, dropping by to introduce themselves.

One of our neighbors really likes to talk and comes over a little more frequently. One night, he rang the doorbell at 9 p.m. just as we were sitting down to a late dinner (we had been painting all day). He was bringing us some oranges from his tree. He chatted with us for about 10 minutes and then left.

After he was gone, I started wondering: Are we supposed to always invite our neighbors inside when they come over? We’re still unpacking, our house is far from tidy and sometimes when they stop by, it’s at an inconvenient time. At the same time, I don’t want to be considered rude.

GENTLE READER: You cannot reasonably be expected to receive uninvited guests -- particularly after a recent move -- so there is nothing wrong with accepting the oranges and saying, “We look forward to being able to have you over when we are unpacked and ready for guests.”

Miss Manners is only relieved that your neighbor also had the good manners -- and situational awareness -- to leave after 10 minutes. She was afraid, when you mentioned the time, that your question was going to be how to perform a polite eviction.
