Wooster: “What do you call it when two people of opposite sexes are bunged together in close association in a secluded spot, meeting each other every day and seeing a lot of each other?”

Wooster: “It is. I stake everything on propinquity, Jeeves. Propinquity, in my opinion, is what will do the trick.”
