This morning on the subway, just as I was pulling in to work, the guy sitting next to me sprang up out of his seat and punched me in the face. Right now I'm a little shaken, but I'm physically fine. My nose is swollen, but I feel that I'm perfectly able to teach class. My doctor, however, feels I should take the day off. Hence the last-minute Tuesday sub.
By the way, they caught the bastard.
