Morgan (7) & Tyla (4) (my daugther's) are playing:

Tyla: I kill you!
Me (from the background): No killing allowed (trying to instill pacifist leanings into children)
Morgan: But Dad, there's always bad guys
Me: Yes, but no killing allowed!
Morgan: So, what do we do with the bad guys?
Me: Put them in jail - no killing allowed
Morgan: What if they get sick in jail and die?
Me: Well, that's different . . . just so long as you're not killing . . .
Morgan: OK! So, you go to jail, get sick and die!
