I realized there are things you do unconsciously in your life that you always do.
I find that when I'm drinking something- especially milk I always stir (Or shake it a bit) it with a spoon after a moment. I do it with soda's even though it's not the smartest thing to do.
Also I tend to brush my hair.. a lot. I don't even realize I am at times. Or I'll brush my hair, set my brush down, and then brush it again. Sooner or later someone will point out that I've been doing it repeatedly. =/
SO the whole point of this thread is to say what things you do without realizing it until someone points it out to you.
