Dr. M and I went to see The Nutcracker last night at the SF Ballet. Shortly after the first act began, a small earthquake rattled through the theater. My immediate thought was: "Great. Either the theater and/or balcony is going to collapse and kill us, or we'll be crushed in the stampede of out-of-town yokels who've never felt an earthquake before."
Fortunately there were no further tremors, neither of these things happened, and the ballet was enjoyable. Dr. M also enjoyed it, partly because I didn't tell her any stories about Mr. Belvedere during intermission.
