Ken :Lily how do you usually go to work?
Lily:By car, what about you?
Ken :I usually go to work by bus.
Lily:Why? I don't understand. You are rich enough to offer a car!
Ken :Yes, I do have enough money to buy a car. But taking public transport is better for the environment.
Lily:You are really a environmentalist!I can never get a seat on the bus.
Ken :Sometimes, but I'd like to take it as sport before work.
