John, it's time to get up.
It can't be time to get up yet.
It is. Hurry up! You'll be late for school.
What's the time?
It's nearly half past seven.
My watch says ten past.
It's slow. Hurry up! The bus goes at twenty to eight.
Are you sure half past seven?
Positive. I'll put the radio on.
It's only seven o'clock. Your watch is fast.
No, it isn't. It's stopped. I forgot to wind it up last night.
I could have stayed in bed for another half hour.
