Mat: Ann, let's go, or we will be late.
Ann: What time is it?
Mat: It is already 10.25.
Ann: Well, we still have about 15 minutes.
Mat: What time did you say the train is leaving?
Ann: 12.05. And it takes only 20 minutes to get to the station by bus.
Mat: Yes, but what will happen if the bus is late?
Ann: Relax, those buses run every 10 minutes, so we have plenty of time.

...........still on the bus..........

Ann: What time is it?
Mat: It is quarter to twelve.
Ann: Oh dear, we will miss our train.
