First of all: none of us IMO has the REAL thick skin.
Second: when I hear people yellin' vs an umpire/coach they're normally sitting on the stands, doin' nothing but that (criticize).
Here in my town we have a said: 'when you do nothing, you can't be wrong'.
Coaches and umpires (and players and officials and...) are the ones who take care of SOFTBALL.
Let the rest of the world behind you with this awareness.

Ciao!
