Sometimes we can take offense so easily. On other occasions we are too stubborn to accept a sincere apology. Who will subordinate ego, pride, and hurt-then step forward with 'I am truly sorry! Let's be as we once were: friends. Let's not pass to future generations the grievances, the anger of our time'? Let's remove any hidden wedges that can do nothing but destroy.
Learning to forgive is much more useful than merely picking up a stone and throwing it at the object of one's anger, the more so when the provocation is extreme. For it is under the greatest adversity that there exists the greatest potential for doing good, both for oneself and others.
Love thy neighbor as thyself: Do not do to others what thou wouldst not wish be done to thyself: Forgive injuries. Forgive thy enemy, be reconciled to him, give him assistance, invoke God in his behalf.
