A: I’ve run out of money altogether. I was so busy doing
my accounts I didn’t have time to get to the bank today.
B: I’ll give you some money.
A: From your piggy bank?
B: No, from here.
A: Oh, no. That’s the cookie jar. I could do with a cookie actually, but this has no money in it.
B: Ha, ha, ha, oh yes it has. I’ve hidden some money in here as well.
A: Ha, you hide your money everywhere, don’t you?
B: Aha. How much do you need?
A: Oh, 5 dollars. I pay you back.
B: Oh, you don’t have to do that. You can keep it.
A: Oh, no, no, as soon as I get a chance to get to the bank, I pay you back.
