Argh!!! Gonna wring a child's neck when it comes home

Eider came in panting, happy, obviously had a blast, but doing what? I looked out and the gate is WIDE open! Who knows where he went or for how long! I didn't even know he was gone! He obviously had a blast though. Child was running the wheelbarrow through that gate today and I chewed him out just a little while ago about making sure to close the gate after himself.

Grrrrrrrrr! At least Eider came back in one piece! Can't say the kid will come back in one piece when I get ahold of it.

We have TONS of gates on this place and I have been trying to hammer it into their little pea brains for YEARS to SHUT THE GATE and LATCH IT. This one child seems particularly determined to ignore my lessons

Anyone care to help me devise the plan of torture? I have a large hole that needs digging. What say another hour of digging for punishment? Wish I had some fence posts for him to put in as punishment. I like to tie the punishment to the offence but I can't think of anything fence related at the moment.
