"Da plane, Da plane..."

Luke has discovered airplanes! (Good thing we practically live in the DFW airport.) Since there are constant airplanes flying over our neighborhood, he had discovered that when he hears one, he will soon see it. The other day, it was nice out so we had all the windows open. We were in Luke's room and he heard an airplane and he immediately looked up looking for a plane, pointing to the ceiling. Poor thing, he turned to me like "where is it?"
