Just to continue the scouts / murderers theme, my mate’s dad and my dad used to take turns running us to scouts. When it was my mate’s dad’s turn, he’d give his ten year old son the car keys and send him off to get the car out of the garage, drive it down the back lane and up the front of the street to the house!
On the way to scouts he’d regale us with tales of his scouting days, which mostly seemed to consist of forcing other kids to eat various horrible things (small dead animals, whole boxes of matches and the like). Even as a kid I knew something wasn’t right with him.
About ten years later, he strangled his wife in the Costa del Sol, chopped her into little pieces and dumped her in various bins. He got caught and so far as I know is still in prison.
