I always do this when I am stress or try to think about stuffs very hard.

I make my hair massy when I try to think about stuffs.

Normally, I put my hand on the head and start "dry" washing my hairs.
I didn't know I was taken a picture by Caman, a friend, when I did that.
She knew I was going to "dry" wash my hair.
It is funny.
I know I do that, but it is nice to see a picture of myself.
