F³A: Offsides of Life

I know, I know, I'm talking about soccer a lot.  But I love the sport, and many of the rules could translate to life.
Many are confused by the offside rule.  Here is a short explanation: an offside foul is called when an offensive player, or attacking player, is passed the ball and there are not at least two opponents between him or her and the goal line. Usually, these are the goalkeeper and one other defender, but not necessarily.  
Basically, you are gaining advantage in an unfair way.
