So why is it that no one here uses profanity without substituting characters? Apparently, we all know where the line is drawn, and so do the players.
Okay, that comment was only 10% serious. If it's a simple d@mn it, I definitely let it go. When they drop a very loud "f-bomb," I have a hard time just letting it slide, especially at the league I previously mentioned. It's not that I have sensitive ears. You should hear me at work when someone breaks their computer. "I have to go unf*** So-and-So's computer." However, if I don't enforce the rule in that league, I won't be asked to call there again.
*shrug* Not my rule. I just enforce it.
