The point of this thread is to discuss your unusual habits, not harass people for being different. So quit the trolling, and get back to the topic.
I've always taken great satisfaction in peeling things. It may be gross, but I'd always peel off the dried skin that comes after a bad sunburn.. it feels funny =p. I also peeled off the sticky-plastic stuff on textbooks while in school.. the teachers never noticed, thankfully. Same goes for tape or other things that come off easily. I used to take apart my split ends.. I stopped doing that in late high school, cause it's bad for the hair haha. Fortunately, I don't have split ends anymore since my hair is shorter.
