So here's the deal, I use sort of multiple personalities to get through life.

Well...

You are very devious and cunning, and do things for either sexual benefit or just for the sake of experimentation. You feed off of others being butthurt/emotionally affected by your schemes.
Taylor is the anti-Annie, if you will. Unlike you, she is calm, understanding, and seeks to help the person she's talking to. Her main goal is to ensure the other person is doing alright, even despite what you do to said person.
Leah, from the little bits that I know about her, is quite shy, and has to truly know a person before she will open up to them.

I hope my descriptions are accurate, and make total sense. If you want, you can even describe mine (Alex) and my alter-ego's (Chelsea) personality.
