"You can trust your feelings."
"Why mine more than hers?"
"Because your feelings are the feelings of a beautifully sane and perfectly balanced person."
"How can you possibly tell? You don't know me."
"I know your type."
"My type isn't me. You can't tell by that."
"You can if you're a physiologist."
"Being a physiologist won't tell you anything about me."
"Oh, won't it?"
"It can't."
