A Class Half-Empty

So, uh... I think I've adopted a spider? Or - because spiders truly are the cats of the arachnids - a spider has adopted me? See, there's this lovely little arachnid that's been floating about my room for some time now. Months, if she's new. Years, if her kind live that long. Every Spring there's one little pale spider with dark paws that roams around my house, usually spending a significant amount of time in my room. On my desk. While I'm there. And I know it's doing quite well for itself because, over time, it has grown from the size of my thumbnail to the size of my whole thumb, and it has gone from a pale tan to a full, dark brown. This fuzzy lady lopes about my room on her graceful legs. She gingerly climbs down my walls. She scurries under the notebooks and untended mail and criss-crossing cords that I can never seem to clean off my desk for long. She curls up in little burrito-holes of fabric or paper where she can find them. She wanders around the top of the shower curtain while I'm in there. She's just... here. And she doesn't seem to care that she's in the room with a fucking giant that could easily squash her - even on accident. She's a brave little thing, as evidenced by her scooting out in front of my mouse while I was using it and giving me a near heart attack. Because, you see, she gives me the heebie-jeebies something fierce. I'm fine with spiders - at a distance. She is not at a distance. But she's also just... here? Being a spider? Like, it's clear she bears me no malice (after scooting out in front of my mouse, she turned her back on me and calmly curled up in an aforementioned burrito-hole for a bit, just hanging out like a cat on my desk, then moved on), and I bear none for her. But my hind brain sees those long legs curling about the ridge of some paper and hauling her over it and out of view and just.... ugh. UGH. Anyway. I sure hope I'm not setting myself up to get envenomed by a spider that suddenly decides it's gonna get territorial with a giant. There are some legit dangerous spiders where I live, but they're usually bigger and more aggressive than this so I think I'm okay... but I also don't really know my spiders, y'know? She seems pretty chill for now, and I'm content to let her go eat whatever mites and ants and bugs and the like live in my carpet and closet and walls, and occasionally scare me half to death. It's just I never thought I'd befriend a spider. If that's what's happened.
