It would have been much nicer if I hadn't done those things to begin with. Unfortunately, growing up and coming to my senses took longer than it should have.
As for hand gestures--I had different exposures, different cultures, when I was a child: upper New York State (rural) and New York City. I don't remember any hand gestures from the country, except for violent ones (oh dear, yes!) In New York City, people are expressive with their hands. It's part of the language. Though, 'flipping' the wrong person off can get you into a lot of trouble. I'll admit to the judicious use of all my fingers at some time in my life 😇
Thank you for that lovely picture. I've looked at it several times now.
