Thanks, Mom. But I have no time. I have to clean my bike.

Are you going to school by bike? Why not go in your dad's car?

We shouldn't drive the car today.

Why?

Because today is World Car Free Day. It's time to do something for our earth.

I see, I think I should go to work on foot today.

Great, Mom! Thank you.
