I constantly scratch at velcro
since i was a kid, i used to use my left hand to hold anything with velcro on it, and my right hand to suck my thumb. i grew out of the sucking thumb, but i still love to scratch velcro!!
idk if thats even how i should explain it, but i use the "prickly" side and i sometimes use my teeth to make it a bit longer and i just stick it under my nail and go back and forth. it hurts sometimes, but if i stop i'll feel an urgency to use velcro again.
nowadays i buy velcro and stick it onto small stuffed animals so i dont look as crazy when i carry random objects with velcro. i used to use my velcro shoes as a kid, mud and all, to sleep.
just wondering if anyone does this? everyone else i tell looks at me like im psychotic.
