A. How many people are coming to the party?
B. Well, there are some of my friends from work about twenty-five.
A. Have we got anything for them to drink?
B. There's a lot of wine and beer in the fridge.
A. That's isn't enough. I'll go to the supermarket. Have you got any money?
B. Have a look in my purse.
A. There's nothing in your purse! I'll use my credit cards. Do we need any bags of crisps?
B. No, we don't. There are twelve bags in the cupboard.
A. OK, I'll go to the supermarket now.
B. I've just remembered something. Everyone is arriving at 6.00 so you need to hurry.
