I think it’s clear to anyone who has beaten me senseless with a crowbar without fear of retribution that I am not a violent person. While others were studying the physical arts of ju-jitsu or boxing in their youth, I busied myself perfecting the sort of intellectual wit that encouraged those other little ninjas to demonstrate what they learned in karate class. But I never cared for physical violence. Why bother inflicting fisticuffs, I rationalized, when I could undermine someone’s confidence about their purchase of a Kajagoogoo album? A black eye can heal in a matter of days, but an emotional scar could require decades of therapy. I still think I made the right choice.
