I do things on a regular basis that cause others to inquire the number of times I was dropped on my head as a baby.I guess that's a quirk.
My friends ask me the same thing when im smarter than them. It suprises me.
I bite the inside of my mouth a lot.Like, just chew my lip.
I randomly start singing while I go about daily tasks. No one seems to mind since I can sing fairly well.
when i eat sandwiches i always flip them upside down
