It's time for bed.
But I'm not sleepy, Mum. Can I stay and watch more TV?
It's already half past eleven. You have school tomorrow. You'll sleepy all tomorrow, if you don't sleep well tonight.
I know. But I promise I won't be sleepy tomorrow. I work really hard.
Don't you have the exams coming up soon? I'm sure you could spend more time preparing for those.
Oh, I nearly forgot the exams.
You do well in maths, but your history is not good enough. Am I right?
Yeah, I guess so. Maybe I can go to sleep now and get up early to review the lessons tomorrow.
An excellent idea. Work now and play later.
I know you're right. School is more important than TV. Can I watch one more show, then go to bed.
No, now it's bedtime.
