maybe coppola just couldn't think of anything profound enough for him to say.
i know that bethany and josh have to yell at me now...
Actually, Coppola did script something for him to say. So there.

But ultimately she decided it was more powerful if you didn't hear what he said, because that way the audience can co-create meaning in it. Which is more powerful than if he'd said say "I had a good time and I wish I could stay but bye. I'll always love you." or something like that.
I still don't understand why you always bash LiT, Linds, especially since right after we saw it you talked about how awesome it was. I think you're fallen prey to the "everyone likes it so I've got to mock it" virus.
