Disappearing Cell Phones

Monday morning we had to attend a meeting at school about how the car line works at school. My son had to attend with me and thought it was all pretty funny. The director of the school gave us permission to talk on our cell phones until we turned the corner to pick up the kids then our cell phones had to disappear. Alex looked at me with surprise and whispers, "Mommy, how will you make your cell phone disappear? Can you do that? Can Mrs. Plum really make you do that?"
