Making arrangaments

Guillem - Hi, Lluís. I've got a new computer. Do you want to watch it with me?

Lluís - Yeah, of course. When?

Guillem - How about Saturday night?

Lluís - Sorry! I'm busy. I 'm going to cinema.

Guillem - I'm free on Sunday morning. What about you?

Lluís - I'm not doing anything.

Guillem - Great! Come to my house on Saturday.
