Just remember, for every one of those games, there's always the game where you have to call 60 fouls because the players just aren't good enough. Or the game where both coaches are whining and the players roll their eyes after every call. Or the game where there's one parent that argues every call against their kid (and their kid's best friend), while yelling for 3 seconds during the tip drill going on under the basket. Or even the game where you come in late and make a grand entrance by tripping over the ball.
Some of us forget we're out here because we enjoy doing this. Put a copy of the good games in your memory bank, so you can withdraw a couple of those memories after the bad ones to help you get through them easier.
