ordinary rec league game early in the regular season, you probably have some issues if you're crying after a loss. If it's something you've worked for over a period of years and a loss means it's over, I can completely understand crying.
I remember living in Kansas when KU had been ranked number 1 from the preseason poll all the way to the elite 8 where they lost to eventual national champion Arizona. Some of the KU guys were crying after the game. A lady in my ward at a party said, "I can't believe they're crying. It's just a game." I felt like saying, "Picture working at a job for a few years and putting your heart and soul into it. Then one day, unexpectedly, you get fired. You cry. And I say, 'It's just a job. Go get another one.'" But I didn't say anything. Instead I'm left with the memory of how clueless this lady was.
