Girl: How much butter?

Boy: Oh, about one spoon.

Girl: OK. What else?

Boy: Next, cut up some tomatoes.

Girl: How many tomatoes?

Boy: Well, maybe one is enough. Put the tomato on the sandwich. Next, cut up an onion.

Girl: Sounds good. What about the cheese?

Boy: Next, put some cheese on the sandwich.

Girl: How much cheese?

Boy: Not too much, but you can put more if you like.
