In attempting to translate one’s expectation into an agreement, it gives the expectation a reality test. If the expectation can be accommodated or translatable into reality, it is feasible. If the expectation cannot transition to reality, it requires modification or elimination. Depending on the person and expectation, the modification or deletion could be a herculean effort. However, changing their environment/reality to accommodate their expectation, could also be a herculean effort or an impossibility. Cognitive dissonance will remain if both are left unsettled. Depending on the situation, from an energy/resource/effort perspective, it is often always easier to change or eliminate one’s expectations.
