This morning I went to the dentist's office.

I went up to reception and said, "Hi! I have a 10:30 cleaning." The woman looked at her schedule, and then she looked at her computer, and then she looked at me. "You're not on my list."

"I have the reminder you mailed me right in here," I said, digging in my backpack. (I'm between purses right now.) "Here it is!" I read the postcard. "Did you know there's a Thursday the 17th in March, too?" I asked.

"See you next month," she said.
