G/T: Greg, what are you taking on the trip?
G: I want to take some light clothes, my mp3 player and of course mobile phone.
G/T: I think you should take a paperbacks too.
G: Why do you think so?
G/T: They are very useful and you don't know when they're necessary. What else you want to take?
G: I forget about compass. It's very important.
G/T: You're right. I propose you to pack the playing cards too.
G: Oh, yes. There's nothing better than playing cards with friends.
