Did you guys make any games up?
Did your teachers ever try to get you all involved in a game or activity at lunch, even though you wanted them to just butt out and let you be kids?
We played Shark Infested Custard, a variation of tag which used the markings on our school yard as safe places/islands. There was a small team of sharks, a team of swimmers and one lifeguard who indicated when it was cool to swim, and which island we had to get to when the sharks came out to tag us. I can't find any rules online so I can only assume it was made up by some of the older kids.
I remember a few occasions when all the staff would come out into the yard and engage the entire school in a giant hokey cokey. I have no idea why, but it happened a couple of times a year. I'm cringing just thinking about it.
