Should we ref at schools we are associated with

[Chin Ref]

I'll try to avoid refing the game with the team/player associated with me. However, I have one tricky act when if I need to do that type of game. First, pre-game with both coaches that if the no. of foul calls are 9 to 1 in favour of the friendly team, that is the game's character, not because of the refs. Secondly, T the friendly team early in the game for tic-tac thingfor laying my ground rule. Any future 'Homer'saying heard will not be tolerated. Any advise??
