In high school I was in a play called The Curious Savage. In it a psychologist (or psychiatrist?) quotes Lord Byron: "And if I laugh at any mortal thing, 'tis that I may not weep." Words to live by, I'm telling you.
I've been a little stressed out reading Comedy of Errors, which sounds a little silly now that I write it out loud. The misunderstandings! The threats! The what-ifs! On the page, denuded of the silly costumes and the near misses and the slapstick one would see on the stage, it's less clearly a comedy. In fact, I am thinking about Othello as I am reading it, because both plays show how easy it is to be misled by appearances. Sometimes it ends well, as in Comedy of Errors. Sometimes it doesn't.
I didn't expect Antipholus and Dromio to leave me feeling glum.
