There are always 3 sides to a coin. People sometimes neglect to acknowledge the edge. Plus there is the internal part of the coin. People who say that there are two sides to the coin, are communicating a partial truth. There are 3 sides to a coin. The irony of that saying, is that it’s meant to open people’s minds to the possibilities of other perspectives, and then the saying fails to communicate the perspective of the third side. That’s why it might be better to state, ‘There are always 3 sides to a coin.”
This is a simple way to promote expansion of awareness in people’s minds. Give them something that they have never heard before. The risk is that you’ll be labeled as weird. But, the new saying might become accepted. And the people saying it might be seen as having broken though to yet another higher level of understanding.
