Story cut short - Had u-14 game today, one of players had previously bullied my brother and therefore we had had arguments in the past, with threats (but never escalating) towards violence. I didn't let this effect my game and saw him as a usual player and he respected i was the referee and in charge and i had no problems with him in the game, but it made the game very on edge and difficult for me as i didn't want to be seen as biased because of our past, should i let the situation slide and have that team again or should i inform my appointments officer to not assign me this team again, bear in mind the game was clean and the past didn't affect it to much, however i did hear him saying some things before the match which proved him and his team were all on edge, and may have lead to a tricky game had i made a bad decision within it.
