- Um, I don't think I'm gonna be able to make it for lunch today. I'm sorry.

- I met a guy on the train, and I got off with him in Vienna. We're still there.

- Are you crazy?

- Probably.

- What, he's Austrian? He's from there?

- No, no, no, no. He's passing through here too. He's American. He's going back home tomorrow morning.

- Why'd you get off the train with him?

- Well, he convinced me.

- I mean, actually, I was ready to get off the train with him after talking to him a short while. He was so sweet, I couldn't help it.

- We were in the lounge car, and he begin to talk about him as a little boy seeing his great-grandmother's ghost. I think that's when I fell for him.

- Just the idea of this little boy with all those beautiful dreams. He trapped me.

- And he's so cute. He has beautiful blue eyes, nice pink lips. Greasy hair! I love it.
