Trust.
What is trust?
It’s a band stretched to its elastic potential, which (if you paid attention in Physics) requires equal amounts of effort. This ‘effort’ requires the constant reassurance that the other person wont let you down.That they share the same understanding that you do and that they are ready for every term this agreement offers; the good and the bad.
A tub of Honesty, a can of Wholeheartedness, a pinch of Compromise and a willing Sous chef
These promises all translate into unimpeachable relationships.
Well, in a perfect world they do
Just don’t let go of your end
