[Corvidae]

I don't nail bite. Instead, I

-twirl hair
-chew up wires and pens
-pull back hair
-suck on my fingers
-gnaw on my joints
-push my eyes in
-mess with my eyelashes
-pinch myself
-shake leg
-tap finger
ect.

I do a lot of things so yeah. Usually I don't notice until I've been doing it for a while though. lol
