I usually leave spiders alone. If nothing else, they're a minor inconvenience when I'm trying to work out an equation on my work desk, or when i have to whizz in a public bathroom. I prefer to not engage them, because they usually set up shop in fly-heavy regions so I can leave a relatively comfortable life.
Still, I have a Phobia of them spindling down and crawling into my mouth. I know I'd likely swallow it, but if my TONGUE of all places got bit, I'd have a mental breakdown. Being in Texas sucks though, since we got Brown Recluse, Black Widow and this other spider. Which are all lethal. And they can bite into you and force a surgeon to remove an entire muscle region. My step-dad got bit in the leg by a Recluse, now that part of his leg is skinnier than the rest.
My actual dad got into a dusty spare work-suit from a closet while he was at a refinery. Long story short, he had to whip out his *rooster* in front of everyone, get a doctor to pull off the thing (the Recluse was latched onto with unbelievable force to the head region). His schlong didn't work right for a month. I had a month of peace in that period of my childhood, which I shall never forget. Oh, but immediately afterwards the mental scarring continued.
