AS others here have posted in sit #1 dealing with a teenager can be difficult
at times. She did not ultimately however challenge you or your integrity. As for sit #2 if he did not whisper "learn the rules blue" he's gone. As a fellow umpire he should know NEVER question a umpires understanding of a rule publicly. I would think better of him if he asked you (quietly if you were sure of your interptatation of the rule. Calling you out publicly especially over something as trivial as this tells me he's wound a little tighter then most of us.
