I'm still of mixed minds about this; I was the world's foremost arachnophobe for all of my early life. Well, a general bugaphobe; the more legs it has, the less I like it. (Which came in really handy, considering the number of centipedes and millipedes occupying my house back east...

) Conversely, it was drilled into me, from my earliest childhood memories, that as a descendent of Robert the Bruce I'm forbidden by family policy to harm a spider. (A spider was Robert's inspiration to escape from his English jailors and retake the throne of Scotland, so they're considered sacred to the Bruce clan.)
Anyone with a true phobia, however, will definitely agree that family tradition has no chance whatsoever against the cause of fear. I initially became afraid of bugs due to inadvertently sitting down to rest for several minutes on a red-ant hill during a family picnic when I was about 4 years old. I still wasn't worried about spiders.
That came in when I moved to southern Ontario. Frequently, I would wake up with wounds along my arms that looked as if I'd been run through a sewing machine. After a few weeks, I asked a locally-raised friend about it and he told me that it was spider bites. That was the instigation of full-scale warfare.
When I was 15, my spider phobia had become so severe that I couldn't whap one with a flyswatter because I was sure that it could run up the handle and bite me before it died. At that point, I owned a Llama XV .22LR semi-auto pistol with a 2 3/4" barrel. To avoid personal contact with spiders, I kept a 5mm starter blank in the chamber. That combination gave a visible muzzle flash of about 10 cm. So, I'd see a spider trucking across the floor toward me, and shoot it. The flash would instantly curl the bug into a little ball and blast it into the opposite wall. I'm pretty sure that the church board (the house was an integral part of my dad's church) puzzled for years over why there were dozens of 10 cm scorch marks all over the living-room carpet.
Now that I'm on the ADD meds, I'm not all that bothered by them any more. I don't like "thick" ones or "fat" ones, but I don't object to others hanging about. I don't want them touching me, but cohabitation is now acceptable.
