Peter: Wow! Look at our rockets. Which one is yours Mary?
Mary: Mine is there. It’s much taller than the other rockets.
Peter: Oh, I see it.
Mary: which one is yours, Peter?
Peter: I’ll show you. This is it. It’s one of the heaviest rockets. Maybe it won’t fly.
Mary: It’s a good rocket. Don’t worry. Where’s John’s rocket?
Peter: This is his. It’s much smaller and lighter than mine.
Mary: And look! Here’s Betty’s. Hers is much thinner than mine.
Bill: Yeah, they’re interesting. This one’s mine.
Mary: It’s one of the tallest ones.
Bill: Yeah. I can’t wait to see them fly. Let’s go.
