I have an idea,
If I were to get a REALLY big and hairy spider as a pet, outfit by the front door, and name it something cute. And probably but pink stickers in the tub thingy,
No one would ever visit me as an adult. I'd be free of people who annoy me. All I'd have to do was make sure it wasn't lethal, and I'd have no worries at all with it being there. Plus I think it'd be cute to have around.
