Hi, John. What are you doing here?
I'm waiting for the bus.
Where are you going?
I'm going to the station to meet my sister.
Oh, is she coming by herself?
Yes, the train comes in about half past four, but it's twenty past four now. I have only ten minutes!
How often does the bus run?
Every ten minutes. I missed a No. 1 bus 15 minutes ago, and the next one hasn't come yet!
