My worst reaction was in a under 14's rep competition, where I toed the ball into the ground, and back to the wicketkeeper. I was given out, when I was walking back, the umpire yelled out the the scorers that I was out LBW. I didn't know what was going on, so I went back to my batting partner and captain, showed him the cherry on my toe then just decided to take the decision and walk off.
We got real close, if we won we could have won the whole comp. I was on 17 at the time, set and looking for a good score. Was majorly disappointed about that decision, and still am.
