write a letter to a punctuation mark

Emily runs a blog called em-dashes and suggested readers of this blog might be interested in a contest asking you to write a letter to your favorite punctuation mark. I obviously owe quotation marks quite a bit, but have some affection for the semicolon as well (and, come to think of it, the em-dash). I'm busy writing other things right now, as my many open word docs demonstrate, but I thought some of y'all might have fun with it.
