DEAR MISS MANNERS: My closest friend, who is 23 years my senior and does not have children of her own, has shared with me on my recent birthday that she and her second husband have included me in their will. I’ve been told that I will be receiving one-fourth of their estate -- an equal share to her husband’s three children.

Firstly, I have discovered with this announcement that the thought of losing my best friend is utterly heartbreaking. Wrapping my creative mind around her not being in my life has been a journey in itself.

I have already begun a small grieving process, as well as shoring my strength for speaking at her funeral. Preparation, I know, is healthy, builds character, and will allow me to discuss different aspects of her passing while she is still vibrant.

The announcement has now had almost four weeks to settle in, and I feel I must write a letter of thanks or acknowledgment. But I do not want to insult her generosity. I feel I cannot discuss this with anyone close, for the knowledge of wealth transference seems to bring out the worst in people. I’m looking for honest advisement on how to proceed.

GENTLE READER: Is your friend’s death imminent? Or is she merely steeling you for the inevitable?

It seems to Miss Manners that you have indicated the latter -- and that you need not work yourself up quite so intensely, quite so soon. With any luck, it will be a long journey -- and yours is a difficult momentum to keep up.

However, since you are so moved, you may certainly write a letter telling your friend how much she means to you, and that while you do not like to think about losing her, her announcement has touched you deeply.

And then let it go. Surely, neither you nor your friend want to spend the duration of your relationship fretting about its demise.

DEAR MISS MANNERS: A co-worker from another country visited our location in the U.S. for several weeks. When he first came here, his command of English was somewhat limited. His English improved significantly during his stay.

On his last day, when he came by my office to say goodbye, I found myself tempted to mention how much his English usage had improved. I bit my tongue, since I’d heard that it’s not proper to make personal observations of this type, even though it’s complimentary, since it could be taken the wrong way. Was this the right thing to do, or would it have been OK to say something?

GENTLE READER: Personal comments, even complimentary ones, on someone’s body or hygienic habits are not proper in the workplace.

But observations and compliments on personal achievements are -- especially, Miss Manners cautions, when they directly relate to the job being done. Just be sure that they are not prefaced by pointing out how terrible the person was at that skill in the first place.

DEAR MISS MANNERS: How should I respond to co-workers who wear earbuds?

I start talking to them without realizing they have these gadgets plugged into their ears. They miss half of what I am saying, and then I have to repeat myself. I find this very frustrating.

GENTLE READER: These co-workers should convey a signal (pointing to their ears, half-embarrassed, half-apologetic) so that unsuspecting conversationalists are forewarned.

In lieu of that, Miss Manners suggests that you make up your own system of sign language as you approach them (one arm outstretched in questioning mode, one finger pointing to your mouth) so that you are not continually forced to repeat yourself. It would also not be remiss for you to start going to someone else with any important issues, so as to discourage any non-work-related earbud activity.

DEAR MISS MANNERS: I’m a freelance singer/stage director and music activist. I also do some voice coaching. People will introduce me as “a voice teacher,” or even worse, as “a music teacher.” How can I avoid these embarrassing situations without seeming ungracious? Should I just tell them in advance what to say? Seems kind of egotistical!

GENTLE READER: Your accurate title is quite a mouthful -- and Miss Manners confesses that she is not entirely sure of its meaning. Others, no doubt, feel similarly. That you find the title of “music/vocal teacher” to be embarrassing is ungracious, but not for the reasons you state. Miss Manners suggest that you come up with a succinct way of describing your professions that satisfies you. But she permits you no more than three words to do so.

DEAR MISS MANNERS: My husband has been diagnosed with cancer and is undergoing chemotherapy. In addition to his life-threatening situation, we are dealing with an etiquette dilemma.

A woman from our church keeps bringing us casseroles, which are always very large and very terrible. None of us can eat them, so we end up throwing them out.

The problem is, this lady thinks of herself as a good cook and always asks how we liked her casseroles.

I don’t want to hurt her feelings, and have told her how nice she is to bring them (true). I have finally settled on saying, “There’s nothing like a good home-cooked meal.”

But what I really want is for her to stop bringing them. This is not a close friend, just a casual acquaintance, and I don’t know why she has made our family the focus of her charitable contributions. But she is adding stress to our already stressful situation. Is there any nice way to discourage her?

GENTLE READER: “You are so thoughtful to cook for us, but Herbert has such a limited appetite. Since it is only the two of us, I’m afraid we are still eating the previous casseroles you so kindly made for us.” While Miss Manners fears that this may not discourage the woman completely, with any luck, it will at least temporarily delay her production.

DEAR MISS MANNERS: As people are now telecommuting to work, as I do, how does one avoid unwanted people at one’s door?

In my job, I have to use extreme concentration and I feel that I should not be interrupted in the privacy of my own home. I had a custom sign made and posted on my door that says, “By Appointment Only; Absolutely No Soliciting.” That was the most polite thing I could come up with.

However, I find that people still ring my doorbell asking things like, “Would you like to sell your car?” (If I did, there would have been a “For Sale” sign on it.)

In my job, I can lose many thousands of dollars if an important call is interrupted by the door, so I get quite stressed. “No trespassing” signs don’t help, either. I can’t ignore the doorbell for wondering if it’s an emergency. I would enclose the entire yard with a locked fence, except I have to have deliveries made, and I could not carry them up my steps. How would you handle this?

GENTLE READER: By first taking a deep breath.

As a longtime telecommuter (so long that the term did not exist when she began), Miss Manners is sympathetic to your problem. But if you commonly have emergencies that show up at your doorstep, she wonders what you did before you worked at home.

Now, at least, you can smell or hear when the house catches fire, something that was probably not possible in the office. A workspace out of visual sight of the front door, and a quiet doorbell, should solve your problem.

DEAR MISS MANNERS: An organization that I am part of raises funds for scholarships and awards for students in the local school district. In 32 years, we have given over $500,000 to students.

About six years ago, I noticed that the organization no longer received a thank-you in any form -- written, emailed or text -- for the scholarships or awards from any student. Many members of my committee tell me that thanking anyone for a gift is no longer something students do. I have said that a thank-you for a gift is still the proper way to go.

I am seriously wondering if it would be proper to remind the students that thanking people for their gifts is still in vogue. Or would that be considered tacky in today’s society?

GENTLE READER: Expecting thanks for a favor bestowed is never unreasonable, or subject to fashion, whether or not it is commonly given.

The questions, then, Miss Manners thinks, are: 1. To whom thanks should be addressed, and 2. How to change students’ behavior without being rude.

One thanks a person, which in a corporate setting would generally mean the boss. But charities have donors, to whom the students can be asked to write. By giving the students a specific donor to thank, you will benefit the institution (whose donors will be pleased), improve the recipients’ manners -- and avoid the ban against demanding your own thanks.
