I was inching along in rush-hour traffic the other day, and I saw a man in a truck next to me with his hand sticking way out of his window.  He was holding something in his hand — it was small and rectangular, so I thought it was his phone — and I thought, “He’d better not drop that!”  Another car blocked my view for a couple seconds, and the next thing I saw was a different man in a hatchback behind the truck stop his car, open his door, lean out, and pick something up off the road.  It turned out that the man in the truck had dropped a pack of cigarettes out his window so that the man in the hatchback could have a smoke!
