Model 2 Where to walk dogs?
Bob: There’s some talk of a businessman building a dog park in Shanghai.
Laura: Really, what on earth for?
Bob: Apparently there is a law against having dogs on the streets.
Laura: Does it mean that the dogs have to stay inside apartments at all times?
Bob: It sounds pretty cruel, doesn’t it? Maybe the park is a good idea.
Laura: Maybe they should just allow people to walk their dogs on the streets.
Bob: But in many large cities where dogs can be walked, the streets are a mess. I heard Paris is the worst.
Laura: Couldn’t people just clean up after their dogs?
Bob: Would they?
