I have a pet wolf spider that lives in the room my wife keeps her plants in. Except it isn't a pet because I don't feed or care for it and if my wife finds it she'll insist I move it outside.

Thing is, I'm pretty sure I have moved it outside. Several times. It hangs out in one of the plants, and my wife likes to move them outside sometimes. And it's doing a great job keeping the flies from leaving that room. So Shelob stays.

I feel like some of them know. I have one spider in my shower and every time i take a shower i forget and almost drown it. Then i say something like: gosh darnit Toby, get outa here and i put her in her usual spot again.
