Watching animals is a past-time I enjoy. You never know what will happen next. One would think that animals are smarter than humans but that is not always true. One hot day about mid-afternoon, I was trudging between the house and the garage when I spied a sparrow lying on its side in front of the door - it was not there just five minutes previous. My first instinct was that some animal had just tried to make it lunch, but there weren't any animals around. My quick guess was that it tried to enter the garage through the darkened window and was knocked unconscious. As I watched, its leg began to quiver and twitch. Sure enough, in a short time it was on its feet; revived, and trying to wobble forward. It fell over, lying there for a short time, then, hopped back to its feet. It stood for a while, soon ascending in flight.
