DEAR MISS MANNERS: My husband is a paraplegic and uses a wheelchair. When we became engaged, friends, family, colleagues and even acquaintances thought absolutely nothing of asking me whether he was sexually capable and able to father children.

Not wanting any bit of that conversation, I would normally reply with “How would I possibly know?” and then change the subject immediately.

I thought that these sort of inquiries would end when we were married and I became pregnant, but now the same people are asking me how my child was conceived, and if artificial means were required.

My husband is good mannered and laughs off these sort of offensive questions, but I’m afraid that I’m much more irritated. I need a proper line of defense from Miss Manners before I really blow my top.

GENTLE READER: No, no, Miss Manners would have you take an opposite tone -- that of a patient parent having a difficult conversation with a curious young child:

“Well, it’s like this: When two people love each other and want to be close ...” Then you can trail off with, “Wait -- I don’t know you well enough to be having this conversation. Surely there must be someone in your family who will explain to you how babies are made.”

DEAR MISS MANNERS: I work in a physician’s office. The physician was ill several years ago and the patients could not help but notice. The physician does not discuss this illness with people.

When patients ask me directly, “How is Dr. So-and-So? Did he have illness XYZ?” I am at a loss as how to respond. I usually say, “Oh, he’s fine,” or “I’m not sure about XYZ,” and try to divert the conversation back to why they are here.

I feel uncomfortable lying, as I do know the answers to these questions. If I say something like, “You will have to ask Dr. So-and-So,” or “I’m not at liberty to discuss this with you,” it may come across as rude or like the illness is more dire than it may be. Do you have any suggestions?

GENTLE READER: “You’ll be happy to hear that all medical information in this office is kept confidential. I’ll tell him you were kind enough to be concerned, but you needn’t worry.”

DEAR MISS MANNERS: I am uncertain how to handle the matter of a wedding registry. I don’t like the idea of a registry, but friends and family have told me that they consider not having one to be a thinly veiled cash grab, which seems even more distasteful. What would be the best way to avoid causing offense?

GENTLE READER: Really? Your relatives and friends are unable to imagine that you are not trying to extract something from them, so that if you don’t demand goods, you must be hitting them up for cash?

And that it is more unseemly not to beg than to hand over your shopping list?

Miss Manners is aware that there are indeed people who think that way, but she urges you not to succumb to them. They will just come up with other cynical judgments. Not liking the idea of a registry is an excellent reason for not having one.

DEAR MISS MANNERS: I attend a very liberal college, and many of my classmates are passionate about decreasing the taboo surrounding mental illness. While I support this cause in spirit, I’m bothered by some of its symptoms.

Specifically, many of my peers apologize preemptively for future slights. Typically, a classmate will say something along the lines of, “I’m sorry if I’m rude to you today; I’m dealing with a depressive episode.”

I recognize that nobody is perfect, and would certainly forgive someone who apologized after being gruff. But a preemptive apology often leaves me uncertain that my peer is even planning to try to regulate his or her behavior. I also feel that any regret is insincere: Because the apologizer has yet to hurt me, I don’t think he or she can possibly acknowledge the pain I (might) feel.

Am I right to be put off, or should I catch up to the times? Is there an appropriate way to express my displeasure with such an apology without seeming to judge a friend’s struggles with mental health?

GENTLE READER: “I am so sorry. How lucky, at least, that you know in advance when you’re going to offend. I’m not sure that I am able to do that, so please forgive me if I accidentally take offense.”

DEAR MISS MANNERS: I have dedicated myself to getting back into the habit of sending regular birthday cards to members of both my family and my husband’s family. This is a habit I was committed to years ago and slowly let dwindle away.

In my planning, I’m making a list, by month, of all birthdays to include. This list has the obvious mothers, fathers and all siblings. Who else is it appropriate to include, or inappropriate not to, beyond immediate family?

We have one niece who is still quite young, so she is going on the list. We also have grown nieces and nephews on both sides and, with the exception of one, we hardly see any of them or know what is going on in their lives. And, to add more confusion, my sister-in-law married a man who has two grown sons whom we’ve met once, maybe twice, and they also fall into the nephew category.

I truly want to get back into the habit of sending birthday wishes on a regular basis, but the last thing I want to do is offend family members by leaving someone out who should be included.

GENTLE READER: Host a family reunion. It seems the most efficient means of getting to know one’s family members -- so that a card has some actual significance when it is sent.

If that is not practical, Miss Manners suggests that you create a letter or email chain where everyone can send their own and extended family’s birth dates. If you are truly dedicated to the project, the number of cards may be extensive. But it may soon drop off as interest and reciprocation begin to wane. At which point, you may save your postage and sensibly start editing the list.

DEAR MISS MANNERS: I am a comic book writer who has long enjoyed interacting on social media with my fans and other like-minded folks about the various superhero and science fiction movies and TV shows that are proliferating the pop culture landscape.

We come to you to rule upon the issue of “spoilers.” With the advent of DVRs, not to mention the various priorities and choices that today’s audience has, sadly, there is no longer an agreed-upon “next day over the water-cooler” type of camaraderie.

Audience members who experience the entertainment first are expected to sit on their hands until everyone has had a chance to see it. The mob has sort of informally agreed upon a week’s time to wait to discuss things, but that seems to me to fly in the face of the immediacy of social media interaction.

As a writer, I chafe at the imperfect solution of prefacing every enthusiasm with a long bar of “spoiler space” or typing the crass “SPOILER” billboard warning across what may only be intended to be a brief (albeit, admittedly, public) discussion amongst pals.

Since there are no established rules for TV and movie spoiler etiquette, any opinion on this matter by an individual is usually dismissed as subjective, which, of course, it is. How are folks supposed to account for the entire audience to be caught up without hearing from the churlish that an innocent post ruined their enjoyment?

An entire cadre of pop culture nerds eagerly awaits your response.

GENTLE READER: SPOILER: Not everyone will like Miss Manners’ answer.

She sees nothing wrong with what you deem a crass warning. By headlining public conversation with it, up-to-date fans will be able to talk freely -- and those who are delayed will have been forewarned.

Miss Manners is aware that people who spoil movie endings have been beaten up -- quite literally -- and those they have wronged deem this retaliation justified. Purposefully ruining others’ enjoyment of popular entertainment is unkind, but justifying violence as a means of counteracting it betrays a society that is clearly lacking in priorities.

In the age of immediate gratification, there seems to be no satisfactory waiting period, so Miss Manners recommends the aforementioned alerts. But she already stated that, didn’t she? See? She even spoiled her own ending.

DEAR MISS MANNERS: My husband and I vacation every year in a beautiful rented condo, which we have opened to our children and one close friend.

Two separate friends have invited themselves to our condo for a week, stating they know we have room. We did not commit to either party, but I know it will come up again.

Is their request rude, or am I reading too much into it? How do I gracefully tell them this is not an option?

GENTLE READER: Inviting oneself when one is not family or explicitly given an open invitation is, Miss Manners assures you, rude. “I’m afraid that unfortunately, we do not, in fact, have room. But we would love to see you if you are in town. I am happy to recommend some nearby hotels or rentals that have similar rates to ours.”
