From The Dark Knight Rises
Not a lot of people know what it feels like to be angry, in your bones. I mean, they understand, foster parents, everybody understands, for awhile. Then they want the angry little kid to do something he knows he can't do, move on. So after awhile they stop understanding. They send the angry kid to a boys home. I figured it out too late. You gotta learn to hide the anger, practice smiling in the mirror. It's like putting on a mask.
