See No Evil, Hear No Evil

— Why do you feel you have to pass for someone with 20/20 vision when you're blind as a bat?
— I don't feel I have to pass.
— Yes you do. It's a sickness in your brain just like if you were trying to pass for white.
— You mean I'm not white? This is a scandal! What do you mean I'm not white? Why didn't you tell me this before? You're my own sister!
