JOHN
Well, you see the house is called The Acacias, and it seems rather silly not to have at least one.
MARY
O, I don't think that matters. Lots of places are called lots of things. Everyone does.
JOHN
Yes, but it might help the postman.
MARY
O, no, it wouldn't, dear. He wouldn't know an acacia if he saw it any more than I should.
JOHN
Quite right, Mary, you're always right. What a clever head you've got!
