“The students’ announcements were lengthy – the longer roll call was, the shorter first period would be – and filled with double entendres: Boys’ soccer is practicing on Coates Field today, which, if you don’t know where it is, is behind the headmaster’s house, and if you still don’t know where it is, ask Fred.
