When I was a kid with a drivers license, we had 2 little kids who like to jump out from behind street parked cars, and scare drivers.
First kid, I told his mom, no response. Next I told his dad, and he thanked me and I thought that was it. Turns out he started watching from his living room, and caught his boy in the act. There was a serious ass whipping and the boy never did it again.
About a year later, I told another kids dad that his boy was doing the same thing. I thought the man was going to kill me, I had to run. He cursed me and told me it was none of my business. Clearly the man is a "wonderful" father...when he was sober, which wasn't often.
