DEAR MISS MANNERS: I am very much a recycler -- some might say "OCD" about it. I have been known to stop my car and pick up trash by the road to recycle it, or fish cans and bottles out of co-workers' trash cans after they go home.

I have a few relatives and friends who do not recycle at all, even though it is available where they live. It causes me minor distress when I am visiting them and see cans and bottles in the kitchen trash can, and I have often secretly "rescued" these items and taken them to my car to recycle when I get home.

The problem is that sometimes I am caught, and I am embarrassed to be going through their trash. But more important, I do not want to appear high and mighty about recycling, as so many do about many "Earth-friendly" issues -- as I am not (well, not really) judging them. I am just trying to rescue the recyclable items at no inconvenience to them.

I generally simply say, "Oh, I saw these and I'll take them home to recycle," but I still worry that they think I am either an insufferable tree-hugger or just plain odd for going through their trash. How should one handle this situation?

GENTLE READER: Actually, it is not your situation.

Yes, yes, Miss Manners understands that the condition of the Earth affects everyone. She also appreciates that you are trying to be discreet.

But the fact remains that rooting through other people's trash is a violation of the trust they place in you when inviting you into their homes. You wouldn't go through their drawers or closets.

It is no use arguing that trash is no longer wanted and that you are only looking for cans and bottles. Trash reveals a lot about how people live their private lives, and it is a violation of privacy to examine it. It's also creepy.

Why do good intentions so often lead to bad behavior? Deliberately causing embarrassment, through financial pressure or public criticism, are now standard techniques for good causes. You, at least, are trying to avoid embarrassing others, although, as you parenthetically acknowledge, you have not succeeded.

So please do not justify one virtue, recycling, by violating another, namely respecting other people's privacy. You must come to terms with not being able to police others -- although you are most welcome to keep picking up the roadside trash.

DEAR MISS MANNERS: What would be an appropriate response when meeting for the first time someone you know you do not really care for? Especially if they say something like, "Nice to meet you," and it really is not nice to meet them? How do you let the point come across without being rude about it?

GENTLE READER: Oddly enough, etiquette has dealt with this problem -- not to cover the churlish situation of disliking someone you have never met, but of reserving judgment about a stranger.

Miss Manners is aware that many people think that "It's nice to meet you" is the polite way of acknowledging an introduction. And in some cases, it may apply -- if, for example, it means, "I've heard so much about you that it is nice to meet you at last."

Otherwise, it is considered to be a bit much. What etiquette prescribes is "How do you do?" which may be rendered less formally as simply "Hello."

DEAR MISS MANNERS: What is the correct way to type Rsvp on an invite: R.S.V.P. or Rsvp or RSVP?

GENTLE READER: Would you consider not typing any of them?

It is not only that Miss Manners doesn't think it gracious to type invitations. And while R.s.v.p. is her first choice because it stands for a sentence, the French polite command, "Repondez s'il vous plait," R.S.V.P. will also do.

But it is amazing how often this is disobeyed. Social scofflaws are more common and more brazen than ever. Gentle Readers report that confronting them no longer produces shame, but rather such insultingly dismissive replies as "I haven't decided yet" or "Well, I'll think about it." (The response to that should be, "Well, it must be a busy time for you, so I'm afraid we'll have to do without you" -- followed by permanent exile from your guest list.)

The widespread rudeness of treating an invitation as if it were an unwanted sales pitch is not why Miss Manners is about to propose an alternative to using R.s.v.p. The rude will be rude anyway, and she does not reward them by abolishing the rules they flout. That would be like dealing with a crime wave by deciding that there is no use having a law against robbery if people are going to commit it anyway.

Rather, she keeps hearing from those who are not clear about what it means.

They know it has something to do with replying to the invitations that carry this notation, and indeed, "R.s.v.p." is now used in English as a noun ("We sent in the R.S.V.P."), an adjective ("We ordered RSVP cards") and a verb ("We RSVP'ed").

But what, exactly?

Some Gentle Readers are guessing that it means answering only if you are accepting the invitation, and others that it means the same as that awkward phrase "Regrets only" (which casts the host as assuming that those who decline feel regret, when they may not). A few believe that it requires an answer only if the invitation is to a formal event. And an alarming number believe that it means that you may bring along as many other people as you like.

Then there are those who translate the French term for "please" literally, as "if you please," and therefore claim that they have a choice.

No, they don't. In a better world, no one would have to be urged to answer any invitation (well, perhaps not an "invitation" to buy something), no matter how significant the occasion. If a colleague asks if you want to go for a cup of coffee, do you just stare back and say nothing?

Miss Manners would like to repeat her long-standing plea that we stop using a foreign phrase and put the request in plain English. The traditional wording is "The favor of a reply is requested." As a concession to anyone who can't bear to give up the idea of foreign glamour, she would even overlook using the British spelling, "favour."

But why not use "Please respond"? Is there anyone who doesn't understand that?

DEAR MISS MANNERS: Does a person ask to use the homeowner's bathroom, powder room or restroom, when visiting their home?

GENTLE READER: If so, it is a rhetorical question, as hosts would refuse at their own peril. But Miss Manners does not consider it cheeky to assume consent and merely ask where the bathroom is located.

DEAR MISS MANNERS: I am in my mid-50s and one of my sisters is in her early 60s. She recently emailed me an invitation to her "wedding" to her female partner. They have lived together for about 19 years.

I have no intention of attending. My quandary is how to decline the invitation. I want to be honest. I want to be polite. I see no way to be politely honest.

If I try to be polite and lie, then wouldn't good manners require me to send a gift? I don't see how I can be honest and not upset her. Should I just ignore the email and remain silent and ignore the invitation?

GENTLE READER: If you are so concerned with being honest, why aren't you frank about asking Miss Manners how to use your sister's wedding invitation to insult her and her fiancee without getting caught?

A wedding invitation is not a referendum on the marriage. The only thing it requires you to say honestly is whether you plan to attend. There is no excuse for ignoring it or replying rudely. Miss Manners assures you that if your sister does not already know that you disapprove of her marriage, your absence will make that clear. And no, you needn't send a present.

DEAR MISS MANNERS: As a woman who is pregnant with my first child and due in a few days, I am curious if there are guidelines in place for relatives respecting one's privacy during delivery.

For the past several days now, I have received a constant stream of texts, emails and phone calls from family members wanting to know if "anything had happened."

While I understand their curiosity is well-intentioned, it has become a bit invasive. If I do not immediately respond to a text message, I am bombarded with phone calls wondering if I am in labor. If I were in labor, do these relatives expect me to stop pushing and answer their call?

My husband and I have told them several times we will certainly call them once our son is born. Is this not acceptable? Has modern technology ruined the privacy expectant parents so desperately need?

Before the dawn of cellphones I highly doubt the hospital would patch a call through to a delivery room while mom was in the process of giving birth ... so I ask, what is the proper etiquette for letting family know that baby has arrived?

GENTLE READER: Actually, they know that the baby has not yet been born, and that they will hear when it happens. This is their way of showing interest -- which doesn't make it any less exasperating for you.

A pregnant lady of Miss Manners' acquaintance complained tearfully to her husband that people kept coming up to her and saying, "Haven't you had that baby YET?" He made her a small placard with a pretty picture of an apple tree and the words, "When the apple is ripe, it will fall from the tree."

On the other side, which she would then turn, it said, "So please be patient."

Well, no, truthfully it said, "So shut up," but Miss Manners cannot bring herself to recommend that when she offers it to you as a rote response for return messages.

As for the delivery room, she suggests that you not bring your cellphone.
