DEAR MISS MANNERS: I am an introvert. I do not enjoy large gatherings of people. Perhaps this is social anxiety, or perhaps I am simply plagued by misanthropy. Because of my preferences, I generally avoid large parties: To others, a large room full of jollity is a joy. To me, it is a chore.

We soon approach the holiday season, with the usual cavalcade of celebrations. I intend to avoid as many of these as possible. However, personal or professional obligations inevitably compel attendance at one or two events.

I am generally happiest if I am seen at the event (thus meeting my obligation), but then left to myself, preferably in a quiet corner where no one will bother me, and I will bother no one else.

Is there a graceful way to execute this without engendering accusations of rudeness or interfering with others’ ability to enjoy the event?

GENTLE READER: Seeing someone standing in the corner completely discouraging all human contact is likely to be a mood-killer. Instead, perhaps you could tell your hosts that you would love to stop by, but unfortunately can only do so for a moment.

Miss Manners warns, however, that if you are only making an appearance, you must make it count and engage in some sort of interaction -- even if it is just to say a kind word to the other introvert who is cowering in the corner.

DEAR MISS MANNERS: I’m a retired professional woman who chose not to have children. Whenever I meet someone new or attend a women’s group, I’m asked, with all due respect, “How many children do you have?”

I consider this question too personal and don’t know how to politely say, “It’s none of your business!” How do I respond without sounding snarky?

GENTLE READER: Especially since “It’s none of your business” has the added implication that there are too many children to count. Instead, Miss Manners suggests, “Oh dear, I knew I forgot something!” with a sly smile and a quick change of subject.

DEAR MISS MANNERS: After I had been at a new company for two weeks, the supervisor sent me an email that was clearly something copied and pasted. It began with, “Dear NAME,” which he forgot to change to my name. Is there a polite way to make him aware of this so that he does not do it again? I doubt it will make employees feel valued, as I was rather hurt by it. I considered responding with “Dear NAME, Thanks,” but held my tongue -- or fingers, in this case.

GENTLE READER: You showed restraint. However, as you rightly pointed out, it would be kind to save him from future embarrassment.

“Dear Sir, I seemed to have received a letter for the wrong person. I would be happy to forward this to Mr. Name. I don’t think I’ve had the pleasure of meeting him, but sadly, it seems that now I am too late.”

Miss Manners is loath to add the use of an emoticon to punctuate the sentiment, but if ever there were a time to show that you mean it kindly and in jest, this would be it.

DEAR MISS MANNERS: I started attending a new church recently, and everything was wonderful. After a couple of visits, Pastor Kyle announced that the church was in dire need of volunteers to work the holiday snow-cone booth. So, right after church, I was the first to sign up. I even sent a follow-up email.

On the day of the event, I showed up early, ready to volunteer. Pastor Kyle told me that there were already enough people working the booth. Then he handed me some tracts that I could go pass out.

I tried to be a good sport and hand out the tracts, but I felt terrible and went home early. Pastor Kyle sent me a text last week inviting my husband and me to a cookout, and thanking me for helping out.

What should I have done when I showed up at the booth, and how should I respond to his text?

GENTLE READER: Volunteering is an important, but somewhat misunderstood, endeavor. The volunteer is something more than a customer (in your case, a parishioner) and something less than an employee.

Pastor Kyle acknowledged this in announcing the nature of the work in advance, so that parishioners would know what they were volunteering to do. But he presumably asked for volunteers because there was simply too much going on for the regular staff to handle everything.

What then, should he, and you, have done when the help needed changed? The answer is for Pastor Kyle to treat you more like a parishioner and for you to treat him more like a boss. He should have apologized for the change and asked if you were still willing to help. You might have smiled and cheerfully agreed. Miss Manners reminds you that a volunteer who increases, rather than decreases, the work for the staff does not generally earn the gratitude of a more selfless volunteer.

DEAR MISS MANNERS: How should criticism be received? A post on social media by a friend of mine included the word “it’s” when the possessive “its” was needed. I commented with “*its.”

She sent me this message: “STOP the English corrections!!! I find this offensive because 1. I type fast and don’t stop to edit every damn word, and 2. of course I DO KNOW English construction quite well!! Stop the nit-picking -- enough!”

I thought the woman’s reaction was an overreaction. I have known her since high school, which is more than 60 years ago. I think her belligerence may be an early sign of oncoming dementia. She will be 80 years old this year.

In any event, I replied: “I am sorry that you are so easily offended. I am unable to send you a message online. Apparently, you have blocked me. I do think that someone who is a professional writer should take care with his or her writing -- and editing.”

GENTLE READER: The internet has indeed been hard on spelling, grammar and etiquette. Eighty-year-olds have been known to write and behave like ill-bred teenagers. But without going so far as to defend your friend’s behavior, Miss Manners reminds you that correcting another person’s grammar is also rude. And, of course, it discourages further communication.

DEAR MISS MANNERS: I have seven 6-foot-tall bookcases full of books, DVDs and CDs, with much spillover. Many of the items are rare, out of print and/or unique.

All too often, friends want to borrow this or that, which I hate. In the past, I’ve had items lost, loaned to a third party or come back damaged. Should I cover up my library, place NO LOANS signs or demand a cash deposit? I’ve even had people ask for decor items on display.

GENTLE READER: Being a good host does not require you to hand over everything that is not nailed down, but it does prevent you from slapping guests’ hands when they reach for a book (an act that, Miss Manners notes incidentally, requires permission).

Signs and receipt forms are therefore out of the question. The next time a request is made, smile sadly and apologize, saying that you just cannot part with that item. But it might be less trouble to move the bookcases out of the living room, rather than the guests.

DEAR MISS MANNERS: A few days ago, I stopped at a small local restaurant for lunch. The place is takeout only, no tables. I placed my order at the counter, waited, and was soon waved over by the cashier.

My meal was just under $7. I handed her a $10 bill. She handed me my food, rang up the bill, then promptly deposited the entire amount of change into the large tip jar next to the register.

I asked her what she was doing and requested my change. She said it was “policy.” I asked for the manager. The manager said that while it wasn’t a formal policy, they’d been doing that “for ages” and “nobody’s really complained.” (Something I highly doubt.)

I again asked for my change, pointing out that taking the money without my consent was stealing. Both the manager and cashier became somewhat surly, but returned my change.

The next day, I was discussing the incident with a friend. She was horrified, and said I was completely out of line to request my change, because one must always tip for service. This started a bit of an argument, since I don’t consider handing me a bag and taking money on par with, say, actual table service in a restaurant. She countered that once the money was in the tip jar, it was no longer mine and I had no right to demand it back.

Was I rude in asking for my change? And are we now required to tip everyone we do business with? Grocery cashiers, gas station attendants ...? This friend is still berating me for my “embarrassing” lack of manners.

GENTLE READER: Too many bosses see tipping as a way to underpay the staff, and therefore remain passive about how aggressively tips are collected. Most -- but not, apparently, all -- draw the line at theft.

Expecting a cashier to make correct change is neither unreasonable nor unmannerly. While Miss Manners shares your friend’s distaste at actually reaching into the tip jar, the fact that your money made it that far does not absolve the manager of his responsibility to make you whole.

Tipping is, by definition, not mandatory. If the boss is concerned about his cashiers, then he can make change for you out of the register -- or raise salaries.
