Don't you know who I think I am?

I jotted this down on the 8th.
It's something, I guess.
And when I say "you" I'm not talking about anyone in particular...until the end. But along with talking about someone else, I'm kind of talking about myself to? I don't know... weird.

What makes us act the way we do? Why does that change depending on who we're with and what we're doing? You can seem like a completely different person each time you're with a different friend.
Which one is the real you? Or is it all you? Maybe you just can't figure out how to put it all together, to combine every side of yourself into one. Is that even possible? Should it be? Maybe not.
Are you trying to be something you're not? Or is that the real you? What about the you I knew? The you I know? I don't know who you are. Do you?
