But since League of Legends is a game of team work, he needs other players to work with him, and when his team mates don't play as well, that's when Colin loses his temper and goes beast mode.
He yells at his friend or brother, calls them "weak!" and types on his keyboard but sounds like he's hitting it. It is the same when he is using the mouse. I call him out regarding his behaviour and I see him make a scowling face.
This morning I am greeted by Colin and his big brother arguing over a game. Apparently Colin has left the game without finishing it because he was sick of his brother not playing as good as he is. His brother was upset that Colin was not a good sport. Losing his cool, big brother gave up, went to his room and slammed the door shut.
What's a mother to do in this case?
Ground them from playing anymore League of Legends until they get their attitudes straight.
