My first game was back in the heady days of September 2014.
Not a great performance on any level, but, the standout moment was 17 minutes into the game there was a handball on the line.
Clear as day, I had a perfect view, identified the culprit, isolated him, gave him a warning. Opposition scored the penalty.
I cant explain why I didn't send him off, just one of those things I guess, never happened again.
My first red came a few years later, for OFFINABUS after a player screamed across the pitch to one of his team mates to call him a c**t, no complaints from anyone.
My first S7 came later that season (I think). Reckless challenge, player won't give me his name and despite his captain intervening wouldn't stop arguing so talked himself into a second caution for dissent.
