I remember being given out LBW for a ball that was rolling on the ground back in primary school. I'm 38. It still annoys.
Even back then they gave leeway to kids who couldn't bowl. Now it seems they are giving favours to kids who can't bat. Sounds like world cricket in general.
I remember umpiring a juniors game many years ago where the batsmen had to retire when they'd scored 30, but could come back in at the end of the innings if there were still overs left - I got severely rebuked by the other umpire who was the coach, when I told one of the bowlers that they'd be better off not getting the little kids out, because then the big kids who'd had to retire would come back in and smash lots of runs. They were too young to learn about strategy apparently
