How you play when it isn't going your way, and why that decides who you get to keep playing with.
Don't slam the ball in an aggressive fashion just because you can. It's the quickest way to get all of your crew game invitations revoked.
Head high, smile on your face, because you're above ground, breathing air, and playing a kid's game invented with whatever was lying around.
Yeah, losing sucks. For complete details, see my tournament record.
But you know what sucks even more than losing? Not having the chance to play with people you know and enjoy playing with.
Done well at tournaments but losing at crew games? Same posture. Don't take it out on the friends on the other side of the net.
Got invited to a higher-level game that serves you a healthy dose of humble pie? That doesn't mean you should take it out on the weaker player on the other side.
The longer version of all this lives in Why You Play.
