What's your true self?

How do you act when you're alone, when noone sees you?

i act something like a cat/kung fu fighter/balet dancer/psycho.

In real life i never confront people or complain to anyone (because im too scared).
Then when Im alone I talk to the objects around me.
If an object drops, or does something I dont want to, I start getting mad at it, stuff like that.
