My 13yo games and gets very cross at a game (I.e. FiFA) when game play isn't going his way. "Ref is blind, that wasn't a foul, etc)
Shouting at the ref like you would watching the TV.
He can get cross playing with others while chatting on the phone but not so much at them still at game play
Anyone in the same boat
I think it's too much, I get passion and it's all encompassing but reallllyyyyyyy...
