DEAR MISS MANNERS: One of the worst technological "advances" has been the advent of text messaging. The expectation with this disease is that everyone is always poised to respond to any inane writing, and if they do not do so immediately, "something is wrong." People sit with their smartphones in the expectation that they will receive something and must respond.
There are very few situations that require instant responses, and most of those can be reconciled with a dialed call. The rest can be handled with an email -- or even a written letter (there's a concept!).
I am a dinosaur. I have a flip-phone that does not send texts (because I refuse to use that feature), but does receive alerts from our bank or police department. We have a landline with an answering machine attached, which does not accept texts.
We tell all our friends, family, neighbors and acquaintances that we do not text, and we do not answer the phone during meals. We do not consider this attitude rude, because we have set expectations. It's really a shame that "instant" communication has become an acceptable/required behavior because there is no real reason for it.
GENTLE READER: There is a phrase Miss Manners would like everyone to learn, in the hope that it would lessen the type of annoyance you express: "The best way to reach me is ..."
People who are welded to their phones may no longer use the telephone function. Many no longer use email. You won't use texting. And almost nobody except Miss Manners writes letters.
Is there any wonder that people seem to have problems communicating with one another? Although, considering the tone of current discourse, perhaps things would be worse if everyone could get through.
