What's your worst habit?

I'm accident prone...everything's my worst habit..T.T

Self-consciousness.
If someone wants me to do something, I don't know how they want it done, so I hesitate for like five minutes, and when they yell at me, I babble like and idiot: "W-w-well, I d-didn't know h-how 당신 want-t-ted it done!"
Gagh
>.<
*facepalm*

i cant say. im a clumsy person and defind as strainge so i say things that always need refrased 또는 are not understood. so a lot of things are my worst hapit i guess.

일 dreaming about Bubbles. ;)

I have a disorder where everytime someone touches me (i.e on the soulder) i need to rub it off on a wall
kinda stupid...i know....

노래 randomly and not noticing it, and biting my fingernails. And cannibalism.

I think it's everything with me: I chew my lip, (which gets real annoying when 당신 don't want to but it just happens... sometimes 당신 don't even realize!!) I'm really self conscious, (I always wear really large shirts when I can fit into sizes that are majorly smaller than that) and I have a smart-mouth. (I don't get into trouble with it anymore---everyone's gotten so used to it around me, and some even laugh at my mean jokes) It's ten times harder to stop a habit than start one. It sucks. :(

Nail biting, and sometimes I bite it too much then the nail rips too far down and it hurts sooooo bad.
