Jesse: You know, it's like...nothing much that happens to us changes our disposition.

Céline: Really, you believe that?

Jesse: I think so. I read this study where they followed people who had won the lottery, and people who had become paraplegics, right. I mean you'd think that...you know, one extreme is gonna make you...euphoric, and the other suicidal. But the study shows that after about 6 months…

Céline: Uhum?

Jesse: Right...as soon as people got used to their new situation, they were more or less the same.

Céline: The same?

Jesse: Well, yeah...Like if they were basically an optimistic, jovial person, they're now an optimistic, jovial person, in a wheelchair. If they're a petty miserable asshole, OK, they're a petty miserable asshole with a new Cadillac, a house and a boat.

Céline: So, you’ll now be forever depressed, no matter what great things happen in my life?

Jesse: Definitely.
