My wife can't stand spiders of any size. She has an understanding that spiders are fine as long as they keep their distance and she can't see them.
We had both of our desktop computers in the home office in the basement and we were doing some gaming together. I hear her announce that there's a spider on the wall near her. I tell her I'll be right there and then I hear this *SMASH*. I'm like, "What the hell was that?!". She couldn't wait a second longer and tried to smash the spider with her keyboard.
