Sara: No, I think he's out probably doing what you're doing.
Jonathan: Getting a crush on somebody else's girlfriend? No, I'm sorry, I just meant I had a really nice time. You know, maybe you should give me your phone number. Just in case.
Sara: In case of what?
Jonathan: In case of life. I just had a really great time and for all we know I wouldn't be able to find you again.
Sara: Well, if we're meant to meet again, we'll meet again. it's just not the right time now.
Jonathan: Maybe we're supposed to meet on British time and we're five hours too early.
