DEAR MISS MANNERS: When I moved into a new home in a Florida resort community, friends and family began to accept our invitations to visit.

My problem is that they refuse to use the brand-new (and very cute) guest towels provided for them in the guest bathroom. The towels are freshly laundered and consist of one full set for each guest, hanging neatly on towel racks.

Upon checking the bathroom two days into our last visit, to be sure tissues and lavatory paper were still in good supply, I noticed that the guest towels were hanging unused, and various mismatched towels of all sizes from a nearby linen closet were being used and draped over the tub and sink. One guest had gone so far as to use a few dish towels, despite the bath towels being on an adjacent shelf!

When I expressed my wonder, the response was that the guest towels are too good to use. One guest said she thought they were only for decoration, although I specifically told her otherwise when showing her the accommodations. Even after inviting them once more to please enjoy the use of the guest towels, my requests were ignored.

Other than padlocking the linen closet, how do I avoid this?

GENTLE READER: Sounds reasonable to Miss Manners. Nothing else works.

Why refraining from using guest towels is the only universally observed rule of etiquette, she cannot imagine. Yes, children were instructed not to wipe their muddy faces on the guest towels. But they were also taught to sit at the table until everyone was finished, to write letters of thanks, to answer invitations promptly, not to break into lines, not to hit others on the playground, and a bunch of other rules that they no longer observe so strictly.

And did they not notice that these items are called guest towels? So they are meant to be used by guests? So that when they are guests, they are supposed to use them?

Even if they were unable to make that leap, you have repeatedly told them that the towels were for their use. What about the rule of respecting a hostess’s wishes? Or the one prohibiting raiding her closets?

The notion that the towels are “for decoration” is bizarre. Your furniture decorates the house, but you presumably allow the guests to sit on it. If you have pretty plates on the table, should the guests not eat from them?

DEAR MISS MANNERS: How do I respond to a thank-you when it is obvious that the person giving thanks believes my effort was way more than reality?

This false information was perpetuated through the proverbial grapevine, not by me. To explain or downplay my actions seems like false modesty. However, simply accepting the thanks could make me appear to be a fraud, if found out later.

GENTLE READER: Yes, but you will be on the record as having downplayed your heroism.

Therefore Miss Manners recommends overdoing it a bit -- ”No, really, it wasn’t much, I promise you” -- in order to make it memorable.

GENTLE READERS: We really must protest. It is the American way to speak up against what is wrong, even if we can’t agree about what is.

With that privilege, Miss Manners is lodging a protest against the use of rude confrontations -- public name-calling, in the streets or electronically -- as a form of protest. She expects to be called naive, cowardly and a lot worse. Vented upon. But then, who isn’t, these days?

There are many legitimate forms of protest: voting, marching, demonstrating, chanting, lobbying and participating in public life -- whether to seek office or to help like-minded people do so. These may or may not accomplish the immediate objectives, but they are important expressions of public opinion that can build strength and ultimately prevail.

Even the rate of failure is not like that of venting, which has never accomplished anything. Has even a single person who was called nasty names stopped and thought, “Well, perhaps that’s fair; I should change”?

Predictably, Miss Manners objects to venting because it is rude. Its target is not only the designated one, but everyone else, as it pollutes the public environment. And we are all aware of how often it leads to violence.

But her deepest objection is that it is counter-productive of the very point it wants to make. And by that, she does not count on polite restraint providing a good example, however valuable that would be. People do not admire their victims any more than those under attack admire their attackers.

It is that public confrontation is so conspicuously disruptive and potentially dangerous as to give those who engage in it the false sense that they have accomplished something. Indeed, they have succeeded in upsetting numbers of people, possibly even some unintended targets who would have agreed with them.

Exhilarated by the attention, they stick with that method, thus squandering any time and energy they might put into the forms of protest that might lead to actual change. Miss Manners supposes that if you oppose them, you should be grateful.

DEAR MISS MANNERS: We received a wedding invitation that we are unable to accept. I wrote a regret and sent it to the address on the reply card. We would, however, like to give the couple a gift. In looking through the invitation enclosures, we found, to our dismay, that the only “item” for which they registered was money to fund their honeymoon.

I find this distasteful in the extreme, and wonder if Miss Manners has any suggestions for gifts for this couple.

GENTLE READER: A begging bowl in their pattern?

DEAR MISS MANNERS: At a party, a woman I know fairly well came up behind me and ran her fingers up and down my back in a scratching sort of way. I asked her to please stop, saying that I did not like it.

Her response was, “I know you don’t like to be touched, and that’s why I do it.” She repeated this comment.

I am at a loss as to how I could have responded. Am I doomed to be hugged and pawed by people I would be comfortable only touching me with a handshake?

GENTLE READER: As your acquaintance considers that annoying people is amusing, Miss Manners hopes that she will enjoy your giving a piercing scream the minute she touches you and shouting, “What are you doing?”

DEAR MISS MANNERS: I am a young woman finishing up her degree at a local community college. I must admit to being very fond of my cellphone; I read the news on it when I wake up, play games while waiting for the bus, listen to music during my ride and so on.

However, even I’m surprised by the number of people who pull out their phones in (what I believe to be) wholly inappropriate situations.

Not only do people take out their phones in class (distracting me and other students who are trying to pay attention to the lecture), but worse, there seems to be NO place they won’t take out their phone.

For example, I was in the locker room after my aqua yoga class, changing back into regular clothes. All of a sudden, I heard a camera shutter go off. Frightened, I pulled my towel around myself tightly and turned around to locate the noise.

As it turned out, it was simply another young woman (fully clothed, thankfully) taking a selfie in the large locker room mirror. After getting my wits about me, I managed a pointed “Do you mind?”, which she seemed baffled by.

Leaving alone my fear at the sound that someone was specifically taking pictures of women in the locker room, Miss Manners, what if she had gotten me in the background of her shot? What if she had not cropped it out? I would be horrified that such a picture of me existed.

Was I wrong to call her out? Was there something else I should have said, either initially or after she didn’t seem to understand my upset? And finally, could I please implore other Gentle Readers not to take photos (or do other public business, such as phone or video calls) in such a private environment?

GENTLE READER: If common sense is not prevailing, you might ask the establishment to post a sign: “No cameras in the locker room -- without a warrant.”

Miss Manners sees nothing wrong with your quite understandable reaction. If you felt the need to explain --and potentially avoid a repeat experience -- you could have said, “I am sorry for my reaction, but I was startled. I do not think that people want their pictures taken when they are in various states of undress. At least not without signing a waiver first.”

DEAR MISS MANNERS: When I was young, I was taught by nuns in elementary school. And when I went home at night, my mother was there to control and teach me.

The nuns would never have allowed the language I hear from children today. I’m not sure how happy they would have been to hear it from the parents, either. I’m increasingly bothered when I hear “oh my God.”

Is there any way to get people to stop? I see videos online of parents saying it, children repeating it. I find it so offensive. Especially that the parents are not teaching the children that they are too young to decide to use such language. They could at least learn to withhold it in public.

GENTLE READER: Or cloyingly abbreviate it.
