Chris, remember at 11:00 this morning you have to call your grandparents. And at 12:00, can you take Fiona to the swimming pool in my car? She's meeting a friend there.
OK. I wanted to watch some TV but it can wait.
Can you get some stamps too? The post office closes at 1:00, but you'll be there at 12:30 if you go straight from the pool.
OK. Anything else?
There are some library books to return, but I'll do that on Monday. Can you wash the car? If you do that at the garage at 1:00, you'll be back here at lunchtime.
All right. So I'll see you at 1:30 and we'll eat then. At 2:00 there's a football match - it's a really important game. After that, can I use the car to visit some friends?
