Peter,

It's the letting go of hate wracking, hate drizzling, hate debilitating stress that forgiveness addresses. The human body hasn't evolved to live with hate. The hunter-gatherer killed its adversary, ending hate. The farmer-mediator, living up to his name, brought the enemy unto his fold, able to feed him without having to fight over plenitude, unwinding hate.

Astraddle hate-fueled high blood pressure, alcoholism, obesity, diabetes, divorce, fights at soccer stadiums, and other self-flagellating scourges, revenge still needles us into writing our own epitaph, "I'll get even with that son-of-a-bitch."

Forgiveness presupposes, damn, what's that word?
