How Much Personal Baggage do you bring?

[TxBktball03]

And I don't mean luggage...

I attended a college women's basketball game today. I'm not a ref yet, but I observe as often as I can. It truly and objectively seemed like the lead ref had brought a bad day to the game. In the first half, he made most of the calls and most seemed very ticky-tack. The slightest brush and it was a foul. He had a permanent frown and even dressed down a coach who used his first name. In the second half, his frown had eased and the officials hardly called anything unless the foul smack of two arms coming together could be heard in the back row.

My question is, do most of you try not to bring your rainy days to the court, and if you do, how can you avoid taking it out on the boys/girls?
