Proper conduct for losing

How to take losing.

Now, when I was growing up, if you lost a fight or got beamed by the ball, you dusted yourself off and
got back into the game. When things aren't going well in a miniatures game you take a deep breath and
rethink your strategy. If it's hopeless, like at  the Alamo, then you find a bit of grit and play till the end.
What you don't do is WHINE or grumble like an old woman! 

This weekend we played the battle of Arsuf. One of the new kids, okay so he's almost 30, still a newbie, was going on about the Knights Templer
and how great they were (one history class and suddenly they know it all)  so we let him play them. Well no sooner did my light Arab cav start shooting them then the whing began.
him "But you shoot and run away before I can charge.' me "that's what bow armed cav does. You have to charge and hope I fail my parthain shot test"
Meanwhile ole Tim, also playing crusaders, had moved his crossbows to challege the light cav, Does newbie notice and take head, no he tries to charge again
and gets caught in the open away from his support. My lt cav whittles him down again while my heavy cav charges in a routs him.
newbie 'Crusader Kinghts are crap! Obviously this game system is geared to favor the Arabs! Why do we even waste time with these rules!'
So let's blame the rules for bad tactics, something done by old and new gamers alike. But what bothers me is the WHINING. Stop spoiling the game for everyone else.
Because that is what you are really doing,  For God's sake show a little grit!
Wait till after the game and discuss the pros and cons then.
And this post isn't just about that new kid, there are plenty of older games, but not wiser by any means, who have been doing this crap for years, No sooner do they they lay out their army then the moaning begins, you'd think you were at a funeral, "well clearly I'm out numbered again' (stop taking elite armies), 'I've lost my general, game over for me' (well stop attaching him to the first charge of every game) "That's not fair I didn't realize irt was rough ground"(next time pay attention at the start of the game or learn to ask before pulling a blunder)
