Quote context

[...]

- You didn't have an answer.

- I don't know. It's funny, I just realized I'm not pissed off anymore my father cut me out of his will.

- You were his friend, you probably knew he tried to contact me a few times over the years. I never called him back. I was a prick.

- If he was my son, didn't return my calls, I'd have written him out. Fuck him.

- But it's not about the money anymore...

- You know, I just don't understand why didn't he tell me I had a brother? Why didn't you tell me I had a brother? Why didn't anyone ever tell me that I had a brother?

- I mean, because it'd have been nice to know him for more than just the past six days.

- Ray! Ray! Ray! Ray! Ray!

- Come on. It stopped. It's all right.
