Perception is reality.
Approaching these situations humbly is key to helping people see what is actually taking place without demeaning their viewpoint. We need to show respect for other's perceptions while working to gently correct a wrong path. This can't be done from a position of superiority or an intrinsic desire to be right. It has to be focused on reconciliation and mutual submission to the real truth not just the truth as we choose to see it.
