One week myself and two friends were being particularly high-spirited and naughty, it was getting close to breaking up for the holidays so think we were just a bit over-excited.
We kept going out of bounds, even onto the staff car park, this was very much not allowed! One of the dinner ladies was an aunt of my friend, she kept telling us to behave and trying to engage us in acceptable activities but we were having none of it on this particular day.
Eventually and not unsurprisingly she lost patience and ordered us to face the wall and calm down.
