The human ego, be it considered in a psychological, philosophical or general sense will always come in a person's way of achieving this rare quality. Only when a person succumbs the "I", "me", "myself" within themselves, can they reach such a point.

There come situations in a person's life, when the only way to gain self satisfaction and to pacify the heart is by screaming and yelling out every insult that he has ever come across. But to kill that desire and override it with the ability to smile and not only forgive the person in front, but also to seek forgiveness for something one may not even be guilty of, is what creates such humans.  

This ability to mould oneself according to the gravity of circumstances and to step forward in saying a mere 'sorry' creates the dividing line between them and us. It does not belittle one to apolpgize, regardless of what the reason may be. In fact, it elevates one's status to a level which very few can attain. 

Most of us would just remain silent, expecting the other to step forward and make the first apology. Why dont we, for once, put aside such expectations and put ourselves in the others' shoes instead? In every situation, where it is difficult to point out one erroneous party, each blames the other. However, from some point of view, neither could be wrong and from another both could be wrong.  

Therfore, rather than playing the Blame Game, try to calm down enough to be able to think outside your own head and picture the situation from your opponent's view. Only then will you be able to see your faults, possibly accept them and hopefully correct them.
