Irene: Thank you Kai, I'm glad I had the chance to talk to you today, you're a nice guy.
Kai: No problem Irene, I hope we'll do it again real soon.
Irene: Kai... Thank you again.
Kai: ...Too soon for that, you don't have to say that till your ride is over. You know how to say thank you... but you still need to learn when to say it.
