Middle and High schools I was a good little boy, me
Primary and Nursery?
Not so good....
Nearly expelled from Nursery and nearly suspended from Primary
In fact...I think the only time I got into a fight after Primary school was with a German kid called Klaus, I forget what the disagreement was about...but I found a housebrick and considered smacking him with it...decided not to (thought the consequences outweighed the benefits) and dropped the brick...then HE picked it up...and I could see that he had no such qualms and legged it...the brick hit me on the back of the foot...so...I carried on running a bit...then let him catch up with me, then put him down.
Any other times I've come close to a fight I've been able to talk myself out of it....
