That "How is your son?" thing is so fun isn't it?
Its about as bad as How are you? and even on your worst days you say "Fine, and you?"
Because we know with most people they don't really want to know. the people I want to know, know how my AS is. I decided that for everyone else when they ask me how he is I say,"John" is "being John". ( not real name) Or he is in a "finding himself mode" and change the subject, hope they get the hint I don't want to talk about it to them.
Some people think I should say more, but explaining his life isn't my job anymore.
