I like to rub the labels in my clothing between my fingers. I'm very picky about what type of label it is; it has to be so that when rubbed it makes a specific sort of sound and feels right.
I'm not sure why I do it, but I know I've been doing it since I was about 6 (and I can remember the exact moment I started doing it, but ignore that part).
I know I can't be the only one, but I've never come across anyone else who does it.
Is it normal?
