My view of ‘reality’ is the product of my life so far - my experiences, my relationships, the things I’ve done (and not done), the things I’ve learned and the emotions I’ve experienced. All of those things, and a whole lot more, have created the filter through which I see the world.
Your view of reality has been built in the same way.
And so has theirs.
We don’t have to agree with someone else’s view of reality, but we should at least try to understand that it was built in exactly the same as ours…
