Bird brain

At the gym where I work out, there’s a red cardinal on the other side of the glass by the treadmills and elliptical machines. It’s been there for days, and it does nothing but try to fly through the window. Persistent, but not very smart. I was thinking about how small a brain this bird must have to spend its days doing this. Then I wondered what the bird must think of the people it watches every day on our side of the glass, frantically sweating on treadmills that don’t go anywhere… I decided to think about something else.
