Nonconformity. . . .

Or "A warning to the parents of my children's prospective spouses :). . . ."

Adapted from Dr. Frederick Perls, and seen on posters all over the U.S.A. when I was growing up in the 1960s and '70s:

I do my thing and you do yours. I am not in this world to live up to your expectations and you are not in this world to live up to mine. You are you and I am I, and if by chance our children find each other, it's beautiful.
