Lynn's Comments: My mother-in-law, having been an elementary school teacher for many years, readily took on the challenge of teaching our children whatever they hadn't been able to grasp in school. She once used a fresh pie to help Aaron learn fractions. My dad-in-law was in the room when she asked, "What do we call the biggest piece of pie?" and it wasn't Aaron who answered but Tom who, smiling easily, said, "mine!"
