DEAR MISS MANNERS: My wife and I live on opposite coasts from our son, his wife and their toddler son. For many years now, my wife and my son haven’t been on the best of terms, although both are almost always civil towards each other.

As a result of this underlying tension, they sometimes send photos of our grandson (via email and social media) just to me. This means that, if I want my wife to see and enjoy those photos, I need to forward them to her. This makes her feel bad, for obvious reasons. Either that, or I sometimes feel that I just need to do nothing and pretend that I didn’t get the photos to spare her the anxiety.

I’m thinking I should email my son and daughter-in-law and insist that they include both of us on all future photo sharing. Is this called for? Is there a better way?

GENTLE READER: Yes. Reconcile them.

Miss Manners fears that sending that email will upset the delicate balance that has so precariously been created. And that your proposal will only drive the two further apart -- or worse, exclude you from getting the pictures, as well.

Facilitating a conversation between them -- without using your grandson as bait -- seems far more practical. After all, as you might emphasize to your son, the child will soon be old enough to form his own opinions, and your son will not want to be on the negative end of them.

DEAR MISS MANNERS: When my mother died after her third battle with cancer, we held a visitation the night before the memorial service for two hours, plus another hour the following day, before the service. There was also a luncheon.

I am very hurt that none of my in-laws attended. Not my mother-in-law or father-in-law, nor my husband’s sister, his brother or brother’s wife. NO ONE. They never sent a card or anything.

My husband made sure they knew where and when the services/visitations were. In my mind, there is no excuse for not supporting their son/brother and his family. When my friend asked my sister-in-law which visitation she was going to, she said, “I don’t do funerals.”

It’s not about her! Ugh.

I’m trying to move on and forgive them, but I’m not sure I can without confronting them about it. Am I completely out of line? Or are they really that selfish?

GENTLE READER: The latter, it seems. Not “doing” funerals is a particularly charming touch. Ugh, as you would say.

Miss Manners sees nothing wrong with holding on to a bit of resentment by way of a somewhat chilly reception next time you meet. If asked what the problem is, you may answer, “Our family was so disappointed that none of yours were able to attend any of my mother’s services” and leave it at that. If an apology is issued, accept it -- even if it includes selfish, unseemly or grammatically questionable excuses.

DEAR MISS MANNERS: I am a divorced guy who is in long-term recovery from drug and alcohol addiction. I have been attending a Sunday morning meeting regularly for years.

Last week, as I was arriving for the meeting, I noticed that my ex-wife, who is newly sober, was there. I left before the meeting started. This group is important to me, but I’m uncomfortable sharing with my ex there. I really want her to find her way in sobriety. Not sure what to do.

GENTLE READER: Is talking to her an option?

Miss Manners does not ask this facetiously; she understands that exes are often not on speaking terms. But she also cannot imagine that even the angriest and most resentful one would not want the same privacy that you do if she is genuinely pursuing better health.

You might send her a message saying, “I was so glad to catch a glimpse of you at the weekly meeting and see that you are doing well. However, in the interest of us both being able to speak freely there, I wonder if you would consider attending at a different location or time.”

If there is any amount of civility in the relationship -- or at least desire to create goodwill with the other meeting attendees -- surely she will see the reasoning in this.

DEAR MISS MANNERS: Our office has one microwave. Generally, people are considerate of smelly food and the like during the lunchtime rush.

But one guy consistently brings in frozen microwave dinners that take so long to cook that the queue gets three or four people deep behind him. He will pop his dish in during prime time, and then leave while it cooks.

Those waiting in line are so irritated with his inconsiderate behavior that they’ll stop the microwave after he walks out and reheat their own meal, resulting in his irritation when he returns after a few minutes. It seems harsh on both sides. Words of wisdom?

GENTLE READER: Get another microwave. Barring that, Miss Manners suggests posting a helpful note that says, “Please limit cooking time during lunch hours to five minutes.” People in offices do so enjoy helpful notes.

DEAR MISS MANNERS: A childhood friend is in town for two weeks with her kid. I suggested a few things that may be fun for kids: zoo, aquarium, etc.

She wants me to watch a movie with them, but does not want to meet before or after the movie, as she wants to hang out with other friends then.

Is there any point to catching up in a movie theater where we can’t even talk? It would have been different if it were the kid’s recital or sports event, but this sounds like an “I don’t want to meet you” invitation.

GENTLE READER: Indeed. Miss Manners supposes that you are lucky the friend did not suggest dropping off the kids with you and not attending altogether. She recommends you head off that option by saying, “It sounds as if you have a busy two weeks. Perhaps we can make plans the next time you are in town and have more opportunity to talk and catch up.”

DEAR MISS MANNERS: This is a work-manners question.

As part of my job, I attend many networking events to promote the company I work for. At a luncheon, some of the other guests and I were complaining about the abundance of mosquitoes this year. A gentleman I had met a few times before said, “We should talk about my products. We have an all-natural remedy.”

We agreed to meet for coffee. At the meeting, I quickly discovered that this was a multilevel marketing company with a pretty bad reputation.

How do I decline this offer while keeping the professional relationship? He is very involved in the same professional circles, and really is a nice man who I will have to continue seeing at a lot of these events.

GENTLE READER: Business etiquette has the advantage of not being overly sensitive to the personal feelings of colleagues because they are not supposed to be a factor in doing business. Miss Manners does not lay this down as an absolute rule, but in the case of your marketing professional, it is close enough.

Thank him for his suggestion while adding that your company is more interested in a competitor. If pressed for a reason, make use of any one of the many meaningless rejoinders in which businesses delight, such as, “They just seem a better fit.”

DEAR MISS MANNERS: Bottled water at a funeral? My sister told me it was impolite. Why?

GENTLE READER: For the same reason you would not bring popcorn: It is informal to the point of disrespect.

Miss Manners will spare you the trouble of writing back to tell her about a medical condition that requires immediate and continuous access to water (or popcorn). Assuming you are not a goldfish, necessary liquid or food (for a diabetic, for example) can be placed in a pocket, allowing discreet access without compromising your ability to give some thought to the deceased.

DEAR MISS MANNERS: Within a block radius of my home, there are three corner delis in which one can purchase canned beverages, snacks, sandwiches, newspapers, cigarettes and lotto tickets.

With growing frequency, while I am waiting in line, someone will come in, nod to (or in most cases, interrupt) the cashier and say they are leaving a dollar on the register. Then they walk out with a paper, essentially cutting the whole line since they have exact change.

A friend of mine says this is acceptable if the patron is a “usual” of the store, and doesn’t see why they would have to wait in line to buy a paper if they have exact change. But if my situation was reversed, I’d simply wait in line without issue.

GENTLE READER: As the transaction has not increased your own wait, the most Miss Manners can allow you is a wistful look expressing sadness that you are not in the position to do the same.

While what you have described does not fit her definition of cutting in line, she does not mean to excuse this technique for lengthier transactions, such as asking for directions or for something that requires more than a nodding cashier.
