I remember my mate had a concussion...We were playing soccer in heavy rain anyhow he stepped on the ball and fell back straight away, I thought he was okay so we went to our lessons...30mins in and I get called to the Head's office and he's sitting on a chair ice cube thingy...on his head and he tells me he lost the football and can't remember what happened?
so he lost his memory, I cracked up in front of the head and I've been teasing him ever since.
IDK what grade that would be classed at O.O
