Think closely about the connection. Believe it or not, talking to an outsider won't help the inevitable situation of confronting the opposing party. Both parties must come to terms with their pride. Being right or wrong when discussing the problem has no relevance to what needs to be accomplished. It only matters that the dilemma is unraveled, and the opponents become teammates.
Confrontation is scary.
Often you might even feel like the underdog in the fight. You must realize that the confrontation can't be escaped. Sure, confronting a person or persons you have a problem with isn't an easy thing to do, but it's the smartest and most relieving. If you have a problem with someone, talk to him or her directly about it, don't go running off telling the whole world about it. It will only make the situation stickier in the end.
