Dee: How is-
Emily: You know what your problem is? You're a stupid optimist.
Dee: I thought optimism was a good thing.
Emily: But you're doing it wrong! There are two kinds of optimist, Dee. Your kind is the stupid kind. If you always expect things to be the best they can possibly be, then you'll be constantly disappointed, because nothing can ever live up to that. The other kind of optimist - the better kind - sees life as it is, but also sees the bright side of it. That's what you've got to look for, Dee! The bright side!
Dee: ... So what's the bright side of all this?
Emily: I dunno. I never said I was an optimist. Just that you're an idiot.
Dee: I see.
