what we choose to remember... or what we would rather forget...

Clementine: I'm always anxious thinking I'm not living my life to the fullest, y'know? Taking advantage of every possibility? Just making sure that I'm not wasting one second of the little time I have...

Joel: Why do I fall in love with every woman I see who shows me the least bit of attention...?

Clementine: ...you stop listening to what is true, and what is true is constantly changing...

Joel: I can't see anything I don't like about you.
Clementine: But you will, you will think of things and I'll get bored with you and feel trapped because that's what happens with me.
Joel: Ok.

Clementine: This is it, Joel. It's going to be gone soon.
Joel: I know.
Clementine: What do we do?
Joel: Enjoy it...
