Rebecca: "Mama, can a snowman fly?"
Me: "No, Becca. In the movies and on television and in make-believe, snowmen can fly, but real snowmen that are made out of snow can't fly."
Marcus: "But Mom, we can make a snowman out of cardboard and put it on a string and fly it like a kite, and then the snowman will be flying."
Me: "Okay… but… ."
Rebecca: "Can a snowman hop?"
Me: "No, Becca, snowmen are made out of snow and are not alive. They cannot hop."
Marcus: "But Mom, we can build a snowman on a jackhammer and then it will hop."
Words fail me.
