Y'know it don't have to be a squirrel. A rabbit or even a cat works fine too. Let me tell you, if life grows mundane all you gotta do is find something dead. But if that doesn't quite do the trick try being the one who kills it instead. Life is littered with hidden speed bumps, it can be good to find them, my friend. Life begets life, or so it is said. But a tiny taste of death will remind you to beget while the getting's good.
