Tolerance

Everything in the world maintain a thin razor sharp edge of equal and opposite forces which keeps them in a stable state. (I believe this is Newton's First / Third Law).

This law I believe aptly also applies to the chaotic world of human relationships.

We always should be mindful of what to give and take in a relationship.

Whereupon a party decides to upset the balance, the state of the system goes to an unstable state and by Newton's laws, it will change the equation or the physics of the system to maintain a new stable state.
