We Should Not Argue
IMHO: Why should we argue when everyone has their own reality? Arguing is like telling someone "what you see is not true. I am telling you the truth!"
We should share, listen actively and be open to understanding the other person's perspective, simply because we live in parallel realities.
In decision making, we can compromise. If someone is 80 and the other is 10, they can agree on 40 or 50. And this is a metaphor. But we should not argue.
The tension comes only when we try to overlap someone else's reality with our own.
