I only ever get mad when I lose, and if then, I had to have played absolutely terribly. I like learning from my mistakes and analyzing them to improve, but when I have a bad game and make way too many mistakes to even begin counting, I get frustrated at myself. It actually happened this morning when I was playing LoL. I was playing Thresh, and fed like crazy. I tried to feed my ADC by flashing into the enemy and setting up an easy kill, but I ended up flashing in the complete opposite direction, missed just about every hook, and could never line up my flays. I was so done by the end of that game, haha.
