I usually don't mess with wasps. To be honest, I haven't used my front door in around four years because there's the tiniest crack between the screen door and the wooden door and they get in there and like to build. One year I opened the door, not knowing, and one flew in.
He lived in the kitchen on the ceiling for a little over a week, undisturbed, until he finally succumbed to the hot southern daytime temperatures while I ate out and closed every door in the house so he couldn't migrate to the bathroom or the bedroom.
That's fine, they can have the front door if they like it so much. I don't mind using the back.
Oh, I can totally see myself doing the same thing! I'm generally uneasy around anything that stings, including bees, even without a traumatic event in my past to explain it - if there was one, it must have been so long ago that I don't even remember. What I do remember is having a wasp in my apartment once, and my crazy mind made it out to look three times bigger than it really was. None of my friends believed me when I showed them with my hands just how big it was!
But it's not just animals either. I also hate getting vaccinated or having blood samples taken because of the needle! It's the sting. Once the needle is in, I can watch the vaccine being pushed in or the blood being sucked out with no trouble, the sight of blood doesn't bother me (I actually find it fascinating simply because it's red), I just can't watch the needle penetrate the skin. Horrors!
(On the bright side: I could never get addicted to drugs that have to be administered via needle!)
