Solutions are linear, not triangular

Let's say that Person A has an unresolved issue with Person B.

The best way to fix the problem, or at least make positive headway, is for Person A to speak to Person B, in love, directly.

The problem that infects a lot of relationships, no matter how personal, professional or - gasp - even within the church, is when Person C is drawn in.

This triangulates the problem.

More of often than not, Person A discussing a problem with Person B to Person C is not a step towards a resolution. If anything, it allows the issue to spread.

I suspect, this is one of the reasons God is so critical of gossip and the best response, when someone brings a problem to you which your not involved in, is to say "speak to them about it, not me."
