When you come across a dead creature, it's always a bit jarring. Being reminded of your mortality and vulnerability is always a bit of a shock. It's a little reminder that nobody—no living creature—can see their end; we can't predict or know or control it. The bird couldn't, and you can't either. It's good to be reminded of this fact of reality every once in a while, especially since we like to fool ourselves. If you see a dead bird, take a moment to pause and consider all those obvious, plain truths that you'd prefer to forget. Being reminded of your lack of control might be an opportunity to reassess what is really important now, at this moment, so that you can reassess how you are living and how you're spending your time.
