P.S. A week later I was out for another walk and came upon a little boy playing with a remote control car on the sidewalk, no doubt his brand new toy. He directed it right into my foot. "That's pretty neat," I remarked, trying to smooth over his odd driving maneuver. "Yeah," he said as he approached, "but I can't get it to start up again from a distance." He appeared pretty happy nevertheless, so I thought he would appreciate my news. "You know what? I saw a drone the other day." He looked up at me with a big smile. "I got one for Christmas!"
