DEAR MISS MANNERS: I just received a wedding invitation with no instructions on how to RSVP -- no reply card, no email address, no phone number.

I do not plan on attending. Do I owe them any reply? If so, should I send it to the return address? Post something to their social media page (the way we usually communicate)? Call them?

GENTLE READER: It is baffling, isn’t it? That with 98,576 methods of communication available to us today, we cannot seem to figure out how to find someone if not specifically informed of the method.

This wedding invitation is a quaint throwback to a time where even with only one form of communication -- a home address -- it was assumed that people could figure out that hosts might like to know how many guests to expect. The proper thing, Miss Manners assures you, would be to use said address and write a letter expressing your regrets. Not, she is sorry to tell you, to shoot them a GIF or a tweet.

DEAR MISS MANNERS: I am of the increasingly rare school of thought that sees my pets as companions, not children.

I love them. I care for them. I train them. In exchange, I get the pleasure of their company. I do not expect them to outlive me, as I do my children. I do not expect them to learn to think independently, as I do my children. And I do not expect them to go to college or become self-supporting, as I do my children.

When others refer to their “fur babies” or call themselves “Mom” or “Dad” in relationship to a dog or cat, I cringe a little inside, but say nothing. But when others call me “Mom” regarding my pet, I’d like to have something to say, without being rude, that makes it clear I don’t see the relationship that way.

I am not sure what term to offer instead. I think if I referred to myself as Fido or Fluffy’s “owner,” I would be seen as completely barbaric. Any thoughts?

GENTLE READER: “Guardian.” This gives you a slightly more personal edge, while also being sufficiently removed from a biological declaration. That, or Miss Manners recommends a look of confusion followed by, “Oh! Peeps is my dog, not my child. Brenda is currently away at college.”

DEAR MISS MANNERS: I have become reacquainted with the woman my father was dating when he died. They were together for quite some time, though they never married. I am unsure how to introduce her to others.

She has the same first name as my sister-in-law and introducing her with the backstory is cumbersome, but without it, feels incomplete. Since they never married, she’s not my stepmom, and calling her a longtime family friend doesn’t feel sufficient.

I’m delighted she’s back in my life, and want the way I introduce her to indicate that. She was my father’s girlfriend 30 years ago. What is she to me now?

GENTLE READER: Your father’s girlfriend from 30 years ago. “This is my father’s dear friend, Alicia. She was like a mother to me back when he was still alive.” Miss Manners is certain that the term “dear friend” will convey the relationship’s proper significance -- without making the details of that friendship unnecessarily graphic.

DEAR MISS MANNERS: Standing at an airport carousel waiting for my luggage, I noticed two small children playing with the moving belt by running their hands along the edge. Their (I assume) mother was some distance away, engaged in conversation, so I spoke sharply and firmly to the children, “Stop doing that!” And they stopped.

As expected, since my words had attracted her attention, I received a nasty rebuke from the mom. Fortunately, my bag arrived, so I grabbed it and walked away without a word.

Did I handle this situation properly? What would you have done? Also, please alert parents of the danger to little hands and feet from the moving belts that are everywhere in our world (airport carousels, supermarket cashier stations, escalators). Most airports have clearly posted warning signs to that effect.

GENTLE READER: Correcting other people’s children is allowed to prevent imminent harm, and baggage carousels undoubtedly qualify. Even if the machinery does not grab them, there are heavy suitcases to worry about.

The intervention, however, still requires tact: a look of concern, an explanation (“Be careful! There is a heavy bag behind you”). Miss Manners recommends this be applied both to the children and to the inattentive parent. This may not save you from a harsh rebuke, but it will generate sympathetic glares from passersby.

DEAR MISS MANNERS: Last year, a friend’s brother passed and I did not attend the viewing or funeral. Now another brother passed, and I would like to attend the viewing. Is this OK? I really don’t have a good reason why I didn’t attend last year’s funeral.

GENTLE READER: Having missed the first is not a reason to miss the second. Grieving relatives are unlikely to quiz you about last year, but, if asked, Miss Manners suggests you express your profound regret that you were unable to attend the first viewing, and change the subject.

DEAR MISS MANNERS: I live in a friendly neighborhood that I enjoy. However, I have been surprised a few times by neighbors who have knocked on my door, asked to come in, and then asked for a tour of my home.

These are people I’ve seen at neighborhood meetings, not people with whom I socialize -- due to the gossipy behavior that I’ve observed, which isn’t my cup of tea. Do you have any responses I can use to avoid their requests to come in, and their further requests to be given a tour?

GENTLE READER: The answer -- to be delivered while standing in the doorway -- is, “I’m sorry, now isn’t a good time,” accompanied by nervous glances over your shoulder.

The glances are meant to convey the idea that something unspecified is going to go terribly wrong if you do not extricate yourself from this conversation quickly. If the neighbor persists, repeat that this is not a good time and ask if they have a card so you can contact them. Miss Manners is aware that most people do not carry personal cards any more, but as you do not want the information anyway, this should not be an impediment.

DEAR MISS MANNERS: My daughter will be graduating from high school in June. She has chosen to enter a four-year apprenticeship program for a union trade.

She would like to have a graduation party, and we would like to host one for her. But a friend questioned whether we should be having such a party since she won’t be attending college, and it might be tacky for my daughter to accept monetary gifts from guests since she won’t be using the money at college.

The friend stated that I might want to put something on the invitation about my daughter not attending college. I do not agree with her thinking. I want to have a celebration for her accomplishments throughout high school, and to also commend her on her choice to enter into an apprenticeship program. We are not having the party for the monetary gifts; we are having the party for our relatives and friends to celebrate our daughter’s accomplishments.

Please help me in preparing a response to naysayers who do not support our choice to have a party!!!!

GENTLE READER: Your friend’s logic is admirably inflexible, if entirely appalling: that the purpose of the party is to raise money from your near-and-dear; that your daughter will be earning, not spending, money; and that therefore, the party cannot go forward.

Miss Manners is surprised that your friend did not anticipate the possibility of expenses during the apprenticeship, but perhaps she was also sneering at your daughter’s plans.

The answer to such objections is the one you gave -- the party is a celebration, not a fundraiser -- though Miss Manners wonders how necessary (or possible) it is to convince such a friend.

DEAR MISS MANNERS: I have been asked for a good way to remind our senior volunteers of their commitments to work a couple of hours a week at the public library bookshelf, where we sell used books and donate the money back to the library. I have just assumed the bookshelf management job, and have never had responsibility over volunteer workers.

GENTLE READER: Managing volunteers requires both firmness and tact. Firmness, in treating the duties enough like a normal job that volunteers comply. And tact, in that you must be more patient and understanding of partial or noncompliance -- and more effusive in expressing gratitude for work done -- than a boss who is signing paychecks.

In the case you describe, Miss Manners recommends something as simple and direct as a sign-up sheet, perhaps followed by an automatic reminder.

DEAR MISS MANNERS: I’m a man in my mid-20s who has started a much-overdue habit of writing physical thank-you notes and personal letters, rather than emails or text messages.

I’m a bit self-conscious about my sloppy penmanship. If I type up personal, heartfelt words on good stationery and sign my own name by hand, will it still be considered appropriate as I continue to practice my penmanship?

GENTLE READER: Handwritten notes are appreciated for the effort they demonstrate -- and too often for their quaint rarity -- not for their legibility. Miss Manners suggests there is therefore no reason to delay handwriting the whole letter, particularly as it will simultaneously provide the needed practice.
