The completed dialogue:
Pam: Here's a turn. Let's play a computer game. It's called 'Time Machine'. It'll take us into the future!
Bob: Yes, good idea!
Thirty minutes later...
Bob: Pam! Your game is over. It's my thought now!
Pam: No, it isn't. I still have a turn. You must interrupt your turn!
Bob: Come on, Pam!
Pam: Don't wait me all the time and I'll finish faster!
Bob: I'm not interrupting you! Anyway, what do you want to play next?
Pam: It's hard to decide. I like this game because I'm winning and I like my new life in the future.
Bob: Hurry up and decide. And I want to play first!
