Henry: I feel sorry for you, Mark. You just don't know how to have fun.
Mark: What?
Henry: It's because you're scared all the time. I know. I used to be scared too. But that was before I found out.
Mark: Found out what?
Henry: That once you realize that you can do anything... you're free. You can fly. Nobody can touch you... nobody. Mark... don't be afraid to fly.
Mark: You're sick...
Henry: Hey, I promise you something amazing, something you'll never forget. Where's the gratitude?
