DEAR MISS MANNERS: My wife and I were invited to two Super Bowl parties on the same night. She accepted both.

I think we should have politely declined the second invitation with, "So sorry, but we have a previous commitment." Beyond the fact that we will be running from one end of town to the other, I think it is rude to go to one party for an hour and then leave. But my wife disagrees.

GENTLE READER: When will you leave the first party -- during the game, so that the host has to get up and see you out? Before the game, so it seems as if something is wrong? After the game, so that you miss the socializing?

Oh, at halftime. Which will interrupt the people who are watching that.

Miss Manners reminds your wife of what many people seem to have forgotten: that invitations should be promptly accepted or declined, and bargaining over the terms is not allowed.

DEAR MISS MANNERS: I have had serious back issues over the years, including several surgeries, and had a hip replaced several months ago.

Since then, despite rigorous physical therapy and home exercise, I have been forced to use a cane. It helps me walk without a significant limp and also helps keep me upright when standing, as I am not quite as steady on my feet as I (and my doctors) would like. I remain in fairly serious pain if I have to stand for more than a few minutes.

My issue isn't the cane -- or the pain, for that matter -- but the fact that, over and over and over again, people ask me why I am using a cane. While I am tired of the health questions in general, what really bothers me is when I reply that I had hip replacement surgery, they often ask how long ago. When I begrudgingly tell them "six months ago," I inevitably get the response, "Well, you shouldn't still need a cane!" followed by a description of their own experience with hip replacement ("I was walking without a cane in two weeks! You need to do physical therapy!") or some similar experience of their friend or family member.

This is often followed by other fun, probing questions like, "Who did your surgery? Was it their first time?" or comments like, "You must not be working hard enough at recovery!"

At this point, I have run out of graciousness. I am beyond tired of the rude and unthinking curiosity, let alone the advice I don't need and don't want.

How do I deflect all of this? I have tried "I really don't like to discuss my health issues," but that never works. Pleading "Can we please talk about something else?" seems to just confirm their false opinions that I am too lazy to try PT or that my surgeon was a quack.

GENTLE READER: "It's handy for when I have to defend myself."

Then, if they go on about what you should be doing, Miss Manners hopes you will smile when you ask, "Oh, dear, do I have to defend myself?"

DEAR MISS MANNERS: Can I send a simple Valentine's card to a man I admire, but from whom I do not expect a response? The card would just wish him a happy day, with no mention of love or romance.

He does not know me, but he has a high-profile public image, so I know of him. I would send it in care of a professional association he is involved with, not to his home address.

I have no intention of following up, although I did send another simple card 20 years ago to this same man in the same way. He thanked me in writing. We have never met.

I would like to sign my name, but I also don't want to creep him out. He is unattached, while I am in an unhappy marriage, which he would know nothing about. I am torn.

GENTLE READER: Why didn't you just send him a New Year's card? As you say, you wouldn't want to suggest that this is about love or romance.

If you can't fool naive Miss Manners, you may be sure that you will not fool the recipient. But as he is apparently a public figure of some sort, you may not be the first unhappy wife who has approached him. It was gracious of him to thank you the first time, but he does not seem to have suggested that you run away together.

So you are talking about fan mail. That seems harmless, although not flattering to your husband -- if you care, or he would.

DEAR MISS MANNERS: Whenever I finish my meals at a restaurant or club, I always fold my used cloth napkin into a square or rectangle and place it neatly on the table. My dear wife (my manners and social behavior critic for many years) now informs me that this is in bad taste and is evidence of a low-class upbringing.

Of course, I value the considerable judgment my wife has rendered over the years, yet every time I think I have solved the issues emanating from my lesser birth, something like this pops up. What do you think?

GENTLE READER: If not for that crack about being low-class, Miss Manners would have sided with your wife. The state of manners is not related to the state of one's finances. There are plenty of rude people up above, as we all know.

If anything, folding your napkin would suggest that your family used cloth napkins at dinner -- not a given for a long time now. Napkin rings would have been issued, and you would have been expected to place your napkin in yours neatly. Folding the napkin might also indicate that your family did not have a laundress, and so the napkins were used for several meals before washing, but that is hardly what one would call low-class.

However, when one is dining out, there is no question of the napkins' being reused. (At least, there should not be.) That is the reason not to attempt to make the napkins look as if they are fresh.

DEAR MISS MANNERS: Sometimes people will ask me for something, and then as soon as they hear the beginning of an answer that they didn't want, they interrupt and quickly insist that they were "just joking."

Take the co-worker who wanted me to work a shift for them (again), or the irresponsible family member who wanted to borrow more money. On the few occasions that I did agree to cover a shift at work or help a family member, the requests were never jokes.

What is the best way to tell someone "no" when we need to, and ask them to drop the "just joking" ruse?

GENTLE READER: Why? The ruse allows them to save face and for you to laugh it off rather than having to decline -- or actually give them what they want.

Sorry, but Miss Manners finds it to be an excellent cover and convenient solution for you. Second only to not being asked at all.

DEAR MISS MANNERS: I've graduated from school and started my first full-time, permanent job. I've never been happier. I have friends, lovely co-workers, and I truly enjoy my field. Also, after 27 years on this Earth, I am finally financially independent and free of my parents.

I don't want to bore you with the details, but suffice it to say that they were extremely controlling. They supported me financially, for which I am extremely grateful, but they made it clear that their support hinged on my absolute obedience. Part of my obedience was hiding the fact that I am a lesbian, because they are very homophobic.

I would like to put all of this in the past, and I've made some great steps! I have come out to everyone else in my life and established boundaries with my parents.

The trouble I'm having now is that my co-workers seem to find "How do you get on with your folks?" to be an appropriate getting-to-know-you question. I like these people and I assume they are trying to be friendly, but I have no idea what the appropriate response is.

Whether it is a peer or a boss, I find myself floundering for an answer that doesn't make me seem ungrateful to my parents or rude to the asker. Is it acceptable to just say that it's personal? Should I lie and say we get along well?

GENTLE READER: "They are doing quite well, thank you."

Yes, Miss Manners realizes that this does not strictly answer the question. But inquiring into the specifics of familial dynamics is impudent and prying -- and a line of questioning that most people would be happy to avoid answering themselves.

DEAR MISS MANNERS: I feel very fortunate to be able to retire early. When people learn of my upcoming retirement, I'm often asked, "What will you do?"

I know it's a common question, but I don't think older people would be asked this question with the same subtext, which seems to indicate I must do SOMETHING.

I do have travel, hobbies and volunteer activities to pursue, but I don't plan to work again. What is a polite response to "What will you do?" that doesn't justify how I'll spend my time?

GENTLE READER: "Enjoy myself."
