What is really bad is when everyone in the gym knows a foul was committed, you know with every fiber of your being it was a player control foul, you have perfect position, blow your whistle and come out strong with "BLOCK!"
Unfortunately there are no holes on the court for you to crawl into...
By the way, this did not happen to me...another official in a camp ran by the guy who had the loudest voice when it came to state tournament assignments.
