Watching a Squirrel One Day

Today in class I watched as a squirrel made it's way up the tree. I got pretty invested too. The squirrel was determined to make it all the way to the top and out to the end of the branches. I watched as he rose above the level of the buildings around him and the branches started to sway under his weight as he would hop from one to the other. He didn't care at all. He was more interested in reaching the end, why I don't know, then safety. I kept waiting, wondering if the squirrel was going to fall. But he didn't. Maybe he was cocky, or maybe they're faultless, but I turned away for a few minutes (I was in class) and when I looked again he was back near the trunk headed back down. Then he disappeared.
