When I stopped the bus to pick up little five year old Chris for preschool, I noticed an older woman hugging him as he left the house.
"Is that your grandmother?" I asked Chris when he boarded.
"Yes," Chris said. "She's come to visit us for Christmas." "How nice," I said. "Where does she live?" "At the airport," Chris replied. "Whenever we want her we just go out there and get her."
