DEAR MISS MANNERS: I detest receiving telemarketing calls. I use my answering machine as a screening device, and try not to answer calls unless I recognize the number.

However, at times I mistakenly answer a telemarketer’s call -- especially if it’s my cellphone and I’m expecting business calls from unknown numbers.

When I do get a legal telemarketing call, I politely inform the caller that I am not interested, and ask them to remove my phone number from their list. This often leads to them talking louder to keep me from finishing my response, while I’m trying to reiterate that I am not interested, wish them a good day, and get off the phone. (If it’s an illegal or automated call, I just hang up.)

I don’t want to be rude in response; no matter how annoying I find them, they’re just doing their jobs. However, I cannot think of another response at that point other than to loudly say, “As I SAID, I am NOT INTERESTED! Have a nice day,” and then hang up on them. Is this acceptable, when they refuse to let me politely and properly end the call?

GENTLE READER: Housebreakers are also only doing their jobs when they force entry into your home. Nevertheless, you should not welcome them.

Unsolicited telemarketing is, at best, an intrusion into your home. Miss Manners does not consider that license for you to be rude, but neither are you bound to treat such calls as legitimate exchanges, for which you must reach a mutual agreement to end.

The word that should follow the declaration of your lack of interest is “Goodbye,” and it should be followed with a click.

DEAR MISS MANNERS: The morning after enjoying a lovely evening, including dinner, at a new acquaintance’s home, I sat down and wrote a thank-you note. The same day, the hostess emailed me a “thank you” for the gift I had brought her, adding that she’d enjoyed the evening. I responded, thanking her for her hospitality.

While I was quite pleased with her email, feeling it unnecessary since she had thanked me in person, I felt like I had been rude by not sending an email thank-you sooner. I was also embarrassed, wondering if she might think I only remembered my manners when prompted by her message.

In the future, in addition to the “snail mail” thank-you note, should I send an email thank-you as well?

GENTLE READER: The issues here are speed versus charm, and the degree of formality required. But you needn’t wrestle with this, because everything was as it should be.

It was odd and unnecessary for your hostess to say she enjoyed the evening, because after all, she is the one who gave it. Miss Manners is reluctant to discourage any expressions of thanks, but, as in your case, this is more apt to puzzle than to gratify the recipient. Wedding guests who have not yet sent presents but are thanked for attending a wedding interpret such letters as dunning them.

That aside, the message was informal enough to be sent by email, the speed of which was incidental.

Thanks for a dinner party is something of a formal requirement, and thus should be handwritten and mailed. Your hostess will be just as happy a few days later to hear that her party was a success.

DEAR MISS MANNERS: I am the manager of a retail chain bookstore. Frequently, I have customers who want to discuss their political or religious beliefs with me or my employees. How can I politely let them know their advice is inappropriate and nip these remarks in the bud?

Sometimes they seem to be provoked by the books we are selling, but their comments are quite personal and not related to merchandise. They are not simply asking for more books related to a particular title, but are outright telling me whom I should vote for, and that I should tell all my other customers to vote for that particular candidate. Others have told me to attend a particular church.

I cannot just pretend to agree with them, even if I wanted to, because then I would risk offending other customers in the store who disagree.

I am happy to serve all customers regardless of religion or political affiliation, and therefore do not feel that a retail store is the appropriate place for proselytizing or politicking. These people don’t seem to do it to other customers in the store, yet they seem to think that salespeople are fair game.

GENTLE READER: Indeed, they are addressing you as a bookseller, which is what you are and how you should respond.

There is no need to address any personal questions about your affiliations. Rather, Miss Manners advises you to say, “Let me think what books might interest you. Do you prefer ones that agree with you, or are you interested in finding out what your opponents are arguing?”

Should they persist, rather than taking up your offer, you should add, “Well, look around. You’re bound to find something that will interest you.” And then excuse yourself to tend to other customers.

DEAR MISS MANNERS: I have been invited to a baby shower for an acquaintance’s daughter. I have met the daughter once, and it was at a group dinner, so we spoke about three sentences to each other. I know the mother from a social circle, but we are not close.

The baby shower invitation is from the mother, and the RSVP is to the mother and daughter. This is not proper! I do not want to attend, nor send a gift, as I do not know the daughter or her tastes.

I might add that many of us who were invited are in the same boat -- and none of us were invited to this person’s wedding, which was recent. What do you think of this situation? How should I handle it?

GENTLE READER: You need only decline, wishing the daughter well. Miss Manners gathers from the whiff of indignation in your tone that you suspect the lady of motives that are not strictly hospitable. That is best not probed.

DEAR MISS MANNERS: How long is the proper time to wear a wedding band after the death of a spouse?

GENTLE READER: As long as it is a comfort to you. And if it is not your ring under discussion, that decision concerns neither you nor Miss Manners.

DEAR MISS MANNERS: For the past 10 years, I have enjoyed hosting a dinner for very close friends to celebrate my birthday with me. The cost for the evening is generally about $5,000, but I am financially secure. No gifts are allowed.

I have to book the table 10 months in advance, and since it’s a high-end evening, the restaurant provides a private room with a nice view and dedicated servers.

The guest list has not changed for six years. The 10 people around the table have known each other for at least two decades. We talk, laugh, drink and tell outrageous stories. No one drives; I hire a 12-seat van to pick everyone up and drive everyone home.

Dirk, one of “the 10,” recently attached himself to a nice boyfriend, Karl. They have been to dinner at my house several times, and we’ve gone to restaurants together.

The problem is that the private room at the restaurant cannot accommodate more than 10 people -- the restaurant is not willing to squeeze in another chair. If I include Karl, I have to evict someone else. I’m not willing to do that. Dirk is adamant that he will only attend if Karl can be with him. He said, “Move into the main dining room and add a place for Karl; you can afford it. Or find another restaurant that can accommodate 11 in a private room.”

I don’t want to move to the main dining room, as the entire atmosphere for the evening will disappear if we are surrounded by 100 people. And I don’t want to move the celebration to another restaurant; I’ve worked with the current place for a decade and I don’t want to change. If it were only a matter of adding a place at our table, I would do so quickly and quietly, but that’s not feasible.

I see four options: A. Cancel the evening. B. Evict someone to accommodate Karl. C. Cancel the reservation and cater the dinner at home, which will result in much work and additional cost for me. Or D. Say “I’m sorry, we don’t have space for another” and let Dirk decide if he wants to damage the relationship.

Am I missing something? Am I being too rigid?

GENTLE READER: It seems to Miss Manners that the restaurant is. She finds it hard to believe that after 10 years of loyalty, it would be unwilling to add a single chair to keep you as a client.

If it insists, do consider other places.

While Dirk has overstepped his bounds as a guest (that “you can afford it” is outrageous), it does not seem worth damaging the friendship. This event, after all, is presumably about the relationships you have with your friends -- and not the venue.

However, if you go to all of this trouble -- and to prevent future guest infractions -- Miss Manners recommends you tell Dirk that the adjustment was made to include him and his beau because they are an established couple. She permits you to pleasantly add, “So he’d better be a keeper.”
