A : Hi B. Long time no see . How are you ?

B : I'm very well. Where are you doing here ?

A : I just came to a seminar on traffic in the future.

B : That is interesting. Can you tell me which means of transportation are used the most by people in the future?

A : That's sure. Like everyone in the seminar I think driverless cars are the best means. Because it helps us go faster and less time.

B : Uhm...! I don't agree with you. If so, the current drivers would lose their jobs.

A : That makes sense. So what is your opinion?

B : Walk !! That will be the best solution for us humans. We can walk to exercise while on the road. It will take less time.

A : I think so too. And it can reduce the environmental pollution in the world.

B : I hope when there is a seminar I hope you will invite me along.

A : Oki! Bye , see you later

B : Okla
