Today was a "mommy and me" tea at the twins’ preschool. In Kembe’s class, there was a wall displaying the answers each child gave to the following question: If I had a million dollars, I would buy my mommy . . . Kembe decided he would spent a million dollars on flowers. A sweet thought . . . but we may have to have a little chat about the prudence of spending that much money on something that will die within the week. Four is a fine age to start discussing return on investment, right?
