I find myself shouting random thoughts out loud whenever I think of something that either disturbs me, shames me, or just pisses me off. But whatever I shout has nothing to do with that thought. I shout something else I'm thinking. Like if I learn some disturbing news, and I'm looking for the leaked Iron Man trailer from Comic-Con, I yell, "I CAN'T FIND IIIIT!" and I'm not even mad about it. I'll just "playfully" say my thought out loud. And no one else is around.
So it's weird.
