Before Sunrise and Before Sunset

i love these movies..."before sunrise" and "before sunset"
there r sum conversations i'd like to post here... i dunno but these movies bring so much freshness in my mind...
it happens when jesse and celine didnt meet after 9 years separated... well, they would actually but celine's grandmother passed away in time when they planned to get reunited.

Jesse: Oh, God, why didn't we exchange phone numbers and stuff? Why didn't we do that?
Celine: Because we were young and stupid.
Jesse: Do you think we still are?
Celine: I guess when you're young, you just believe they'll be many people with whom you'll connect with. Later in life, you realize it only happens a few times.
Jesse: And you can screw it up, you know, misconnect.

Celine: The past is the past. It was meant to be that way.
Jesse: What, you really believe that? That everything's fated?
Celine: Well, you know, the world might be less free than we think.
Jesse: Yeah?
Celine: Yeah, when given these exact circumstances, that's what will happen every time: two part hydrogen, one part oxygen, you get water every time.
Jesse: No, no, I - I - I mean what if your grandmother had lived a week longer, or, you know, or passed away a week earlier, days even. You know things might have been different. I believe that.
Celine: You can't think like that, it's ...
Jesse: No, I mean, I know you shouldn't on most things, but - It's just, on this one it seemed like something was off, you know
