My husband, Peter, and I were surprised that two plates were missing. We stay in our little apartment in Mexico and, while we’re gone, all our dishes and glasses remain in the cupboards. We pack away most of our spices, but we leave the vegetable steamer and the pressure cooker and all the art on the walls. We leave it all in the apartment which, we assume, is rented out to other people while we are gone, although it is hard to know for sure because everything is always right where we left it. But this time, two plates were missing. And I knew where they were.
