Big things happened in sports this weekend, and we (by which I mean me) are going to be vague about all of that (because sports superstitions). But I don't know why we call them seasons in sports (yes, I tried looking it up) but there's something very nice about thinking of them as seasons. They come, they go, they cycle back around again. In the final song of "Hadestown", which yes, I do keep listening to, they talk about how they'll just tell the story again. Of course oral storytelling has an eons long tradition, and we've all had family members tell stories over and over again. It's why retellings are popular (and of course "Hadestown" is a retelling).
But it's also nice to hit the end, or a break. Sports, since that was theoretically what I was talking about, can be so much fun, but also so stressful as a fan. There are high, lows, amazing moments, and sometimes, disappointments. So, when there's a pause, it's nice to get back to all the other parts of your life.
One reason, I say, totally making this up, that we might call them seasons is that like planting and growing, you need a period of rest before you can get back to playing at that level. It's interesting that more day jobs don't embrace the idea of a season of rest, so that you can be in peak condition for the busy season.
