DEAR MISS MANNERS: My fiance and I were visiting friends last Friday night. Shortly after we arrived, I began feeling lightheaded, so I sat down on a stool at their kitchen island.

The next thing I knew, I was face down on their hardwood floor in a puddle of my own blood and vomit. 911 was called and I went to the hospital in the ambulance. I ended up with a 2-inch gash above my left eye, which required nine stitches.

The reason why I passed out and was nauseated was that my blood pressure fell dramatically, for which I am still trying to determine the reason.

What do you do for friends whose kitchen you turned into a biohazard area and who also cleaned up your mess? A card for such an occasion does not exist.

GENTLE READER: What would it say? "Friends like you make vomiting easy"?

Write a thank you note to your hosts for the visit, apologize for the mess and thank them for the clean-up. It would be gracious to offer to pay for any damage -- or you could just reciprocate by inviting them to pass out in your kitchen any time.

Ultimately, Miss Manners feels certain that any friends worth having will be more concerned about the state of your health than that of their floors.

DEAR MISS MANNERS: I got the following email and have no idea if/how I should respond. I've never gotten an un-invitation before.

"If you are receiving this email, it is because you hold a special place in my heart. ... I want to share some big news! As some of you may already know, my fiance proposed to me a few months ago. We have decided to get married at city hall!

"Since our relationship is far from traditional, we thought, 'Why not?!' We are head over heels in love ... so it feels right!

"Anyhow, for this special day we decided to have a very intimate dinner with our immediate family as well as the maid of honor/best man.

"I am writing for two reasons -- one is to share this exciting news! The other is that I do not want anyone's feelings to be hurt. There will be a big party; however, we need to save up our funds first! We expect the actual celebration to be in a year or two, depending on our financial situation.

"It has been great living together so far -- we are so excited to make it official and can't wait to celebrate with you in the future!"

Is this a new trend?

GENTLE READER: Bridal egotism and callousness have been with us for a long time, but there seem to be ever-new variations in expressing it.

To have a private wedding, with or without a delayed celebration, is not objectionable. But the assumption that others are hurt not to be invited to the ceremony is offensive, even in cases where it might be true.

Furthermore, Miss Manners is highly suspicious of a celebration that is so long delayed and so lavish that it requires long-term saving. That certainly suggests that putting on a show, and, no doubt, receiving material rewards, are more of a motivation than sharing the occasion.

You should treat this disagreeable communication as a wedding announcement and need send only congratulations on the marriage.

DEAR MISS MANNERS: I am confused upon hearing references to "American commoners," as in, "Edward VIII abdicated in order to marry the American commoner Wallis Simpson."

Does the phrase "American commoner" have any meaning? If so, can you explain it to me, and perhaps offer me an example of an American non-commoner?

GENTLE READER: When Article I of the U.S. Constitution banned "title(s) of nobility," it had the side effect of rendering the designation "commoner" meaningless. It is nonsense to have the one without the other.

Therefore the only meaning of the phrase "American commoner" is as a sneer, used in circles where the term "American" was once sufficient condemnation. A character considered equally unsavory by the same set, the "American heiress," once brightened British impoverishment by casting a shadow on the family escutcheon. This feat, however, was possible only when more sunlight shone on the Empire.

Today, that same heiress and her cash are more likely to be thought of as your American non-commoner.

It should be noted that Americans often make an opposite mistake about English commoners. In that system, a living nobleman's children are commoners, although they are addressed with the courtesy titles of "lord" and "lady." And yes, this includes your favorite television characters.

DEAR MISS MANNERS: I am 78, my husband is 85. We fell in love and married last year, and now his 60-year-old daughters are complaining that they never got to plan the wedding for their daddy -- and they say they are "family," and that he needs to choose to be with family or with me.

Is this accepted etiquette? Was it really their right to plan our wedding? Or is it the right of the bride to plan and pay for the wedding? Or is it the right of the couple getting married to plan it? Also, since when is a wife not family?

GENTLE READER: Do you really not have a glimmer of what these ladies mean when they say they would have liked to plan Daddy's wedding?

They would have planned it to take place without you.

In any case, you seem to have accomplished it without their consent. Inventing an etiquette problem (there is no Declaration of Planning Rights) is not going to enhance family relations. You should ask for your husband's help in that. But Miss Manners advises you not to tell his daughters to call you Mother.

DEAR MISS MANNERS: Every so often, a stranger buttonholes me and tells me that I look "just like" someone else they know. (I am a woman in my late 30s, but this has been happening for some time.) They then wait for me to say something. What is a proper response?

GENTLE READER: As there is no sensible follow-up to such a comment, any polite response will do. Miss Manners has heard, "I get that a lot," but as that appears to shoulder blame, she prefers an enthusiastic, "Thank you so much for letting me know."

DEAR MISS MANNERS: My sister eloped and quickly became pregnant. They had intended to announce the marriage to family with a spring visit and small celebration, but instead shared all the news after her first trimester of pregnancy.

She is very non-traditional and has never cared to have a wedding or be the center of attention. She waited for a long time before sharing her pregnancy with many people and has been reserved. Similarly, she does not want me to host a shower for her.

Regardless, many friends and family will want to celebrate her new happiness, and I do not doubt there will be many people who would like to send a gift to the baby due in May. The generosity of loved ones is clearly a help to first-time parents, who have many supplies to purchase.

What is a polite and not tacky way to share baby registry information when she feels certain she does not want a traditional shower? Should she do it after the birth with a baby announcement? Or could she share it now with an announcement of both the new marriage and expected arrival?

I realize some people are starting to share this type of information in "virtual" baby showers on social media, but that seems tacky to me. What is your opinion?

GENTLE READER: That you fail to understand what is traditional and what is tacky.

"Traditional" is leading a quietly dignified life, which is what your sister is trying to do. "Tacky" is prodding others, by whatever means, to do your shopping, which is what you are prodding her to do.

Your sister could have announced her marriage in the truly traditional way, and she can announce her child's birth when the time comes. But Miss Manners hopes that she will have enough confidence in her own good taste to avoid attaching to this the notion that others can be "clearly a help" by purchasing supplies.

DEAR MISS MANNERS: I would like to throw a very distinctive theme party. I'd like to include everyone I know, but of course that isn't possible.

I've noticed on social media (Instagram, Facebook) that everyone insists on posting photos of every party they went to, as if to say, "See? I was there too!" I feel this is hurtful to those who could not be invited at that time. I also know some who will be attending would prefer not to have photos of themselves posted to social media without permission.

I would like to either include an insert in the invitation or put up a small sign at the party asking that no one does these things. How can I word it without sounding judgmental or overly restrictive?

GENTLE READER: Have you already chosen your distinctive theme? Miss Manners suggests a "pre-electronic" theme, or perhaps "Upstairs party at the White House -- guards will confiscate telephones and cameras upon arrival."

Barring photographs should be a relief to your feelings as a hostess and those of your guests who do not want to be snapped. For your guests who feel otherwise, it should at least be a novelty.
