I always thought it had something to do with them being at different stages of development i.e chronological age, emotional age and intellectual age being all over shop.I know when my son was in infants and early primary school he couldn't abide any form of cheating or what he perceived as being unfair. There were no shades of grey everything was black and white. He would never say anything at school but when he got home he was SO angry over things like the other kids not playing soccer at lunchtime by FIFA rules

Thinking back I validated his feelings at the time while also attempting to explain to him why other kids do the things they do.

He grew out of it by about 11. He's 16 now and we haven't had any of those dreaded teenage years. Hmmmm, maybe those early years were it.LOL.
