Have you ever done something strange or unusual when you were young? Something out of the ordinary or just different. Something you did when no one was looking. Maybe you cracked your fingers rotated your feet a ritual or action you were compelled to do which you grew out of, or transferred into something less obvious. I did and still do. I used to make my neck crack, a strange looking movement if you saw it, but I made sure no one was looking when I did it. I grew out of doing it....Well I transferred it to another action. I started to crack my fingers and still do at every opportunity I get.
