I worked at a summer camp with a wolf spider as roommate in my cabin. I told him she could stay as long as she didn't bite the kids. All other counselors complained about mice in their cabins but were surprised I didn't have any.

Fast forward to the last week of camp. Stupid loudmouth kid sees the spider and hits it with a broom. Kids all scream and I run back inside. Asshole kid is trying to squish her and I stop him and get her outside. I scold the kid and he is unrepentant. Last morning in camp he wakes up with a swolen lip that is rapidly taking over his face. He isn't having an allergic reaction but his whole face looks like sloth from the goonies. As I put him on the bus to go home he is crying because his mom won't recognize him. "Well, maybe next time leave the spider alone"
