I occasionally get drain flies in the shower, but this time I have a Spider In Residence. I previously had a pretty good working relationship with a shower spider: I would do a series of thumps to indicate I was about to turn on the shower. I would leave a couple of drops of water on the shower insert's top edge. I would fling various bugs into its web. We had a basic understanding. It died, sadly. The new Shower Spider is doing alright, and it occurs to me that there's this complex web of life: my hair in the drain, some kind of fungus is in there growing on it, drain flies eating the fungus and flying up, they are caught by the spider, which then makes a web to catch more flies. So the matter that was once my hair enters the cycle of life and ends up above me in a spider web.
