[ True Story! ] My son (age 6) is seriously into a set of superheros called X-Men. It seems that one of the characters ("DeathLok") caught his interest the other day and he wanted me to explain if the guy was a good guy or a bad guy. "Well Son, he's a little of both.",I said. "He's a mercenary." "What's a mercenary?", he asked. "That's someone who will fight anyone if someone pays him enough.", I answered. Then my daughter (age 9), trying to put it into perspective for my son said: "What dad is saying is he's just like a lawyer."
