Imagine if we all had a single point of agreement. 
Now imagine when/if we hit a point in any conversation where we strongly disagree or it gets heated that we could simply agree to go back to this point and we both then agree to rethink our view point.
Well I think I have found such a point. I call it the Agreement Point.
Could you imagine this point with me?
This would replace the axiom “Let’s agree to disagree”, which closes off difficult disagreements, with something like “Let’s agree to the Agreement Point”, and start again from this point or time to have a break to rethink.
