'I walked out the door...there's no memory left...'

Joel: [in the house on the beach] I really should go! I've gotta catch my ride.
Clementine: So go.
Joel: I did. I thought maybe you were a nut... but you were exciting.
Clementine: I wish you had stayed.
Joel: I wish I had stayed too. NOW I wish I had stayed. I wish I had done a lot of things. I wish I had... I wish I had stayed. I do.
Clementine: Well I came back downstairs and you were gone!
Joel: I walked out, I walked out the door!
Clementine: Why?
Joel: I don't know. I felt like I was a scared little kid, I was like... it was above my head, I don't know.
Clementine: You were scared?
Joel: Yeah. I thought you knew that about me. I ran back to the bonfire, trying to outrun my humiliation.
Clementine: Was it something I said?
Joel: Yeah, you said "so go." With such disdain, you know?
Clementine: Oh, I'm sorry.
Joel: It's okay.
[Walking Out]
Clementine: Joely? What if you stayed this time?
Joel: I walked out the door. There's no memory left.
Clementine: Come back and make up a good-bye at least. Let's pretend we had one.
[Joel comes back]
Clementine: Bye Joel.
Joel: I love you...
Clementine: Meet me... in Montauk...
