Is life fair? NO! Fairness has two sides: what you owe and deserve. Owing and Deserving are Obligation, and Entitlement. We live in an entitled society, where the message is constantly, what you deserve. If you "deserve" or are "entitled" to something from someone, don't they "owe" or are they "obligated" to you because this is the other side of the equation? YES!
The visceral reaction most people have when they encounter entitlement in another person is to recoil or resist, distance themselves, or pull away because this is the inherent obligation reaction to another's entitlement. A few steps down the road is "will-conflict", the most destructive element in all relationships.
