How we cite our quotes: All quotations are from Goodfellas.
Quote #1
HENRY: See, people like my father could never understand, but I was a part of something. I belonged. I was treated like a grown-up. Every day, I was learning to score. A dollar here. A dollar there. I was living a fantasy.
Before he's enticed by the glamour of the mob, Henry is seduced by the idea of simply fitting in and being supported. His own father beat him.
Quote #2
TOMMY: Anyway, she won't go out with me alone unless her girlfriend comes with her, so I figure you come along and go out with her girlfriend.
HENRY: See? I knew it. I knew it. I knew it. I knew it.
TOMMY: You knew what? See? What? What the f*** is wrong with that?
HENRY: When is this?
TOMMY: Tomorrow night.
HENRY: I can't tomorrow night; I gotta meet Tuddy.
TOMMY: You could meet Tuddy. You could f***ing come early and then still go.
HENRY: Tommy, Tommy. Why do you always do this to me?
As this exchange shows, Tommy is basically like Henry's brother. His hot-tempered brother that sometimes needs a favor. He expects that his good buddy will help him get the girl.
