I'm mad at a friend for quitting during our video game.
What makes you upset about it?
He quits a lot of the time.
Why does he quit? It can be frustrating if someone quits a lot, but maybe that means you should play a different game instead of getting mad.
I actually can't get mad. I cheated on him at the game.
If you cheated, it's fair of him to quit since it's unfair of you to cheat. It's just a game, and I think you two can maybe have fun in a different way. How about watching a movie instead?
