If you think of basic dimensional shapes like the square or triangle, we all appreciate that the shape is made up of different angles. While with a square or an equilateral triangle, the sides are of equal length it may seem to differ depending on from which angle one is standing or looking at the shape.
If you are standing at the side of the road and someone is facing you on the opposite side of the road, you will both observe the same traffic, at the same speed, at the same time. Yet with one significant difference: the traffic coming from your left will be traveling to your right, but for the other person, that same traffic is coming from their right and traveling to their left. If we filmed this and shared it with a third person, what would they see? Two identical events from vastly different perspectives.
Daily, we encounter experiences where our perspective will vary depending on the geometric angle from which we view or experience it. Far too much of what we encounter as conflict or disagreement is in fact simple geometry. If we can go back to geometry class, we may appreciate that emotion is not relevant and merely contributes to distorting our viewpoint.
