x365: 2 of 365: Macbeth

Dear Mr. Macbeth,

In grade 3, I told people that I'd read your play, which I hadn't. For several years you haunted me, stalking all my claims to precocity. When I finally sat down to read the play, I discovered that you were a paranoid schizophrenic married to an obsessive-compulsive megalomaniac. How did anyone let you run Scotland in the first place?

And what's your first name?
