What is the man going to buy?

One. What is the man going to buy?
Woman: Is everything ready for the holiday?
Man: I’m just going shopping — I must get those pills I take when I feel travel sick. Do we need anything else at the chemist’s? We forgot the toothpaste last time!
Woman:  I’ve got that. I haven’t got any sunglasses, but I can borrow yours, can’t I? And I’ll get something to read at the airport.
Man: Right.

Two. Which dress is Kate talking about?
Girl: Oh Mum, this dress is still dirty!
Woman: It can’t be, Kate -- rye only just washed it.
Girl:  Well it is. The mark on the collar has gone, but there’s still a small one here — look it’s at the front just below the button. It’s where I spilt some Coke last week.
