Don't ask about the 7. The explanation involves numerology, Ronald Reagan, and Tom Lehrer. Any story you come up with will be more interesting than the real one.
I live in Watertown, near Boston, with my lovely wife, adfamiliares, a tenured professor of classics, and a small black-and-white purring thing named Gus-Gus. I'm a writer, guitarist, photographer, web designer, and musical parodist (as heard on the Dr. Demento Show!). Once in a while, people even give me money for those things.
