Mike: What did you buy last weekend?

Jack: Nothing much. I went to my grandparents' house. They did not play with their old computer anymore, so they wanted to buy a new one.

Mike: Oh, did you help them to set  it up?

Jack: Not really. Granddad knows quite a lot about computers. He works on computers, doesn't he? So he set up the new computer.

Mike: Oh, yes. He got a more powerful computer to surf and play games on, so that's why they got a new one.

Jack: Yes, he did. He loves computer games. I think they're interested.

Mike: Wow! My grandparents do not think like that.

Jack: Well, mine are! Sometimes I play with them!
