DEAR MISS MANNERS: I am developing a presentation on social media to inform students of proper content in regards to the work world and future employers.

Currently, the most widely used standard is, "If you wouldn't want your mom (grandmother, or other family member) to see it, don't post it." However, I do not think this is adequate. Most families have similar moral and ethical backgrounds, and thus may be more lenient with content than the hiring manager of an international company.

What would you tell students to use as their guide?

GENTLE READER: Is there something wrong with saying, "If you don't want a job interviewer or your boss to see it, don't post it"?

An impeccable alternative would be, "Would Miss Manners approve?" You will note that she has phrased it in the conditional so as not to encourage those who think it would be delightful to try to shock her.

DEAR MISS MANNERS: What is a proper birthday toast for someone who is terminally ill?

GENTLE READER: If your concern is that it would be dishonest or disingenuous not to mention the illness, please stop. The purpose of the party, Miss Manners assures you, is to celebrate the birthday and express heartfelt appreciation for the celebrant, and that is what the toast should do.

But under the circumstances, perhaps levity should be avoided. Only on the stage is the toast from Gilbert and Sullivan's "The Mikado" amusing: "As one month you have to live/As fellow-citizen/This toast with three times three we'll give:/Long life to you, long life to you, long life to you 'til then!"

DEAR MISS MANNERS: It seems that more and more TV commercials, TV shows and movies are showing actors talking with food in their mouths. I used to think that was strictly a no-no, but am wondering if that is now considered appropriate.

I sometimes argue with my son over this, but it is hard to persuade him it is not correct behavior when we see it all the time on TV and in the movies. Please tell me it is still considered rude!

GENTLE READER: Not only that, but Miss Manners considers it foolhardy to allow your son to think, much less argue, that television is the place to observe model behavior.

DEAR MISS MANNERS: What is the correct way to listen to someone? My usual practice is to maintain eye contact with the speaker and respond ("I see," "Mm-hmm," "Interesting"), but eye contact seems to make some people uncomfortable.

I have tried looking off to the side, examining my fingernails, contemplating my drink or staring intently at an inanimate object on the desk in front of me. However, I am concerned that these techniques could mistakenly convey that I am not listening, am bored or both.

GENTLE READER: Such actions will indeed be taken as an offensive lack of interest. Appearing to pay attention when someone is speaking is one of the cornerstones of real social interaction.

Miss Manners wonders if the discomfort you have encountered comes from those who have grown up interacting with their friends through a computer screen -- while simultaneously checking their email, browsing for discounts and playing solitaire. Eye contact need not be maintained continuously, and it can be softened by an accompanying smile or nod as appropriate.

DEAR MISS MANNERS: It's long been explained that hats were worn as protection from the sun in times when people spent a great more time outdoors. This makes sense.

And there is ample evidence of this, as in the discontinuance of hat-wearing by a majority of us who spend most of our waking hours indoors protected from the sun by shelter, while those who spend a great deal of time outdoors as part of their jobs continue to wear hats while outside.

Could it be that hats were not worn indoors because there is no direct sunlight, and thus no need?

GENTLE READER: Sun, rain, garbage, oncoming traffic, oncoming athletes, bad hair, no hair -- Miss Manners can think of all kinds of reasons to wear head-coverings, quite aside from the main one, which is that they can look rather fetching.

But in many, perhaps most, cultures (Miss Manners hasn't counted), head-coverings are highly symbolic. The specific rules as to who is entitled to wear what, and when and where hats are required to be worn or to be removed, differ among nationalities and religions, and between the genders.

Symbols being, by definition, arbitrary, they do not meet your standard of making practical sense. But one should not underestimate their emotional power. Failing to cover or uncover the head, according to the particular customs, can be interpreted as a deliberate sign of disrespect, with resulting consequences.

And yes, that applies to baseball caps.

DEAR MISS MANNERS: My husband and I both had pretty horrible childhoods. As a result, we limit our interaction with the relatives that were implicated in those situations.

Unfortunately, that is difficult in regards to his sisters and their families. They and their offspring tend to be constantly involved in some sort of drama, i.e., multiple husbands/boyfriends who all turn out to be alcoholic/abusive; difficulty holding on to jobs and places to live; never having enough money to survive on ... the list goes on and on. Even though they are always broke, they somehow have the money to go shopping, gamble, have brand-new phones and a steady supply of cigarettes and alcohol.

They are constantly begging us to send them money or let them move in with us! Every one of them dropped out of high school to have kids and still can't understand why they are unable to find decent jobs.

My husband and I have worked very hard and we both have stable jobs. While we are by no means rich, we sacrifice so that we are able to save a little. We have simply been ignoring their texts, phone calls and messages for years, but they just don't stop! It's practically reached the point of harassment. How do we make them stop without coming off as horrible people?

GENTLE READER: They already think you are horrible people because you don't support them, so Miss Manners suggests you stop having misgivings about ignoring them.

DEAR MISS MANNERS: I did quite a bit of work for a group I belong to, and the organizers of the event wanted to thank me by taking me to lunch.

I don't like eating in restaurants and never have, and if someone is trying to thank me, that's the last thing they should do. I declined and explained why.

I was told by someone else that this was unkind of me. This has happened before, and I find myself at a loss as to what to do.

Should I accept a thank-you that is uncomfortable for me, or should I continue to explain that a nice note in the mail would be perfectly acceptable? A box of chocolates is always nice, too.

GENTLE READER: And if they gave you chocolates, how could they be assured that you wouldn't give them a lecture on why you don't like eating chocolates and never have? You don't have to accept the restaurant invitation. You may politely decline. But, Miss Manners begs of you, spare the group your reasoning -- or helpful suggestions of what they could give you instead.

DEAR MISS MANNERS: What is the protocol when you receive a formal notice of someone buying and living in a new home?

GENTLE READER: You are supposed to check your contacts list, get out your address book and change the address you have for that person. Miss Manners can relieve you of the fear that you are obliged to help furnish that residence.

DEAR MISS MANNERS: I have small children who are frequently given gifts from family members, some of which we don't feel appropriate for a child (toy weapons or revealing clothing for little girls, for example).

The givers fall into two categories: those who give the items because they say they know we will not purchase them for our children, and those who simply don't have the same point of view as we do about parenting.

At the moment it is possible for us to write a thank-you note stating that we are so touched that the person loves our children and has thought of them, and then put the gift away. However, this will get more difficult as the children get older and become aware of us withholding these gifts.

I wouldn't think of trying to tell people they should buy the children specific things, as of course gifts should never be expected, but I am at a loss of what to do. I worry that someday they will find out that we take the gifts away and be hurt.

DEAR GENTLE READER: Once your children have reached the age of awareness, you can't reasonably take away presents that they were witness to being given. It is, however, well within your parental rights to mandate where and how the undesirables may be worn or played with (i.e., only behind closed doors).

Even if you could police your friends, monitor the exchange or remove the presents entirely, Miss Manners warns you against it. If your children really want them, they will find a way to procure the coveted objects eventually anyway. Wouldn't you rather they do it under your guidance and jurisdiction?
