My daughters and I have been reading all of the Mercy Watson together. They would like to know why you chose "toast with a great deal of butter" as Mercy's favorite food.
Ha! Hello to you and your daughters. Here is the truth about the toast: I was struggling with writing the first Mercy story. I had some of the basics of the story down: it's about a pig who lives with Mr. and Mrs. Watson. Who aren't pigs. But something was missing. And then a friend of mine waxed rhapsodic about toast and the buttering of toast. And I thought: what is missing is what Mercy loves. And what Mercy loves is toast. With a great deal of butter.
