me: Jack, Daddy is going to take you to the bus tomorrow because I have jury duty.
Jack: What's a jury? (brief pause) Why does it doodie?
me: There's no doodie-ing... A jury is a group of people that get picked to decide if a bad guy goes to jail or not. (oh what the hell would you say?)
Jack: Do you get to see the bad guy?
me: Yeah, if you're on the jury.
Jack: How can you be on it if it's people? Is it a stage?
me: No it's people. It's a group so you're "on" the group. Like you're "on" the team...in baseball or whatever?
Jack: Oh. Does the bad guy try to get you?
me: Nah, they have police officers and stuff to protect us.
Jack: (pondering) But what if the bad guy has super powers?
I'll leave this up to Dad the Lawyer. Please explain to your son in 50 words or less. Have fun!
