I have a certain way with words that people associate with generations before mine. I've always "collected" figures of speech, many of which are considered rather archaic these days. When talking to older people, I'm quite often told; "Oh, I haven't heard that one for a long time." I also have a certain kind of reserved, very "English gent", kind of politeness, which has been commented on quite often.
It really interests me, because I think even over my lifetime, there are many social situations which have become far less formal than they used to be. Many times, when I hear people talking to customer service staff, I feel as if they are being rather rude and disrespectful - as if they're taking the assistant for granted. It makes me wonder if this aspect of modern society is actually more difficult to handle for autistic people than previously, when there was a more formal, and so predictable, way of dealing with people, particularly strangers.
