What do you do ...

[snacks]

I just sit quietly...
And stew.

[Yuffie514]

my mind starts to work harder than usual (moving on to clever+):

1) troubleshoot trouble..."escape" plan
2) fidget/move around a lot (gets the mind going)
3) if nervousness can be sub-categorized as trouble, then trouble isn't really that bad as pesky black/brown-ish pesticides that resemble elongated, salted and pickled olives

If I'm incredibly nervous, and am sitting down, my leg will be shaking as I'm tapping my foot like mad. Otherwise, I 'chew' the inside of my right cheek (very lightly, no notable pressure) or rub my bottom lip or clean any tiny, tiny bits of loose skin I can find off my lips using my teeth.

[Fonzie]

I punch random people

[Leen-Leen]

I punch random people

I kinda feel sorry for those people. I'm a little less violent and punch pillows instead, sometimes.

[YunaGirl05]

I usually bit my lip.

[Dynast-Kid]

I am a horrible nail biter. It is my worst habit, and it makes my hands look less pretty. I used to think that I just bit my nails for boredom and not so much nervousness, but when I get nervous, I bit them to the quick in an insanely short amount of time, so I've come to the conclusion that I always bite my nails but I'm worse when I'm nervous. xD

I also tap my desk quite a bit. I'm fidget like a midget when I'm nervous.

I usually start thinking of horrible things. Then my stomach becomes a gymnastic thing and does flips. It makes me feel sick. Then I bite my nails, and hope I don't screw up.

[ValkyrieWing]

I'm definately a nail-biter...T_T

And I tap my foot, or tap the table with my fingers. Of course, this could be a side effect of 7 years of drumming. :P

[Araciel]

i bite my nails normally...don't get nervous often...sometimes i let out a little laugh that seems out of place maybe...can't think of anything else

[Reles]

I'm nervous in pretty much every social situation. I get really quiet and avoid eye contact and try not to draw too much attention onto myself.

[Avarice-ness]

I have this ring on a chain that I've worn since I was a freshman in high school (if not earlier) and when ever I'm nervous I tend to pull on it some or run it up and down the chain.

[Jebus]

I start shaking, hyperventilating, stuttering, my memory blanks, I can't think, I start zoning out, which also leads to black spots forming in my vision.

That's the worst I've gone through, as whatever made me nervous usually ended at the black spot part.

>>> My mouth dries and gets bitter, not a very pleasant feeling..

[Slade]

If I have a pen with me, which is usually the case as I'm an art student, then I'll fool with the pen. I'm pretty skilled with the pen now due to nervous moments :rolleyes2
