A: You know what would be nice?

B: What?

A: It would be very interesting to live in space. Don't you think so?

B: Well, it depends on what it would be like

A: I can imagine it being fantastic. We could together fly around in spaceships instead of driving cars. And we could all live in floating cities that were above the clouds

B: Why would we want to live above the clouds? It would be really annoying when we will want to go to the beach or play football

A: We could fly down. Or other we could have fake beaches and parks in the cloud cities.
