Mistress Page chats with Mistress Quickly as she attempts to drop off her son at school.
Evans shows up and announces that school has been canceled that day.
Mistress Page complains that her little boy (William) is having a hard time with his Latin grammar, and she asks Evans to give him a mini-tutorial.
Evans proceeds to give little Willy a Latin grammar lesson while Mistress Page and Mistress Quickly stand by and watch.

Evans finishes the lesson and calls Mistress Quickly a "lunatic."
