Whew, Nellie, we had an earthquake this afternoon. 5.5, apparently. There I was, eating my lunch, watching Law & Order, and my bookshelf starting to make odd noises. Also, move. I didn't hear any large trucks passing, so it finally occurred to me that we've had an earthquake. One poor cat was meowing away, the other is in hiding somewhere.
Something a little different in my day, that's for sure!
