Back when I lived with my parents, I'd occasionally have roommates: mice. As such, I have a fair share of mice-related memories. They've never grossed me out like bugs (especially roaches), but dealing with them was always emotionally problematic. I probably have some mild form of PTSD from the mice I've had to deal with. Do you like that euphemism, "deal with?" I don't know where that's coming from. Probably from all those mice I've had to kill.
