Rolling paper
Ever since I was a child, I have had the strange habit of rolling things between my fingers. It could be anything small and roughly cylindrical in shape; headphone cords, small metal pegs, and lead for mechanical pencils all work very well. However, because paper is so readily available, it has become my go-to material. I tightly roll the paper into "sticks," or what have been described by my friends as "homemade toothpicks" (I would, of course, never stick one of these things in my mouth after messing with it all day. Yuck!). I have been doing this so long, that I've become something of a paper connoisseur; the smooth thermal paper most store receipts are printed on is the best. It has even gotten to the point where I walk around with scrap paper or an old receipt in my pocket most days. I'll hold on to one "stick" for days at a time and roll it between my fingers whenever my hands are free. This goes on either until it falls apart, or I lose it.
Does anyone else do this? Any explanations of why I'm compelled to do this? Is this normal?
