I was behind the plate that 2nd game, no arguments or disagreements. It was friendly chatter about the game, hitting trends, player errors and blunders. There was definitely no buildup of bad vibes.
A warning is fine if it upset him that much...but confronting a player in that manner is definitely out of the question.
I love 'stew'ing...especially in fall weather. Once I get it out for someone to hear I should calm down.
