I felt something tickle on my knee and looked over and it was a wee roach. And I screamed like one of those dithering sissies who does that sort of thing. I usually don't. Do you scream at bugs and mice and stuff? Are you actually scared of any of those things?
(My building has a roach problem, btw, not like I live in filth and attract them myself. My apartment is usually fairly free of them.)
