Penny: I hate my job.
Leonard: Really? Why?
Penny: Because I don't feel good flirting with doctors for sales. I mean, I know I make a lot of money. But I haven't been happy for a while.
Leonard: Why didn't you tell me?
Penny: Because I know how important it is to you that I'm having some success.
Leonard: That's not true.
Penny: Okay, really? So you'd be fine if I went back to acting and waiting tables again?
Leonard: If that's what you want to do, yes.
Penny: Well, it's not what I want to do.
Leonard: Oh, yes.
