If u really think about it, we humans never can run away from making mistakes. Our entire existance on this earth started from a mistake. be it by design or cruel fate. but that is not the issue at hand.
the notion that one should go about this life exuding perfection is somewhat flawed. to err is human. and from the mistakes we are presented the opportunity to learn. the opportunity to better ourselves. we must allow people to take these opportunities, not because we want them to taste bitter failure, it is because the learning process is part and parcel of becoming human.
it has become commonplace for folks to harp on the mistakes of others no matter how minute it seemingly is. its as if all of the sudden their own past failures and mistakes are non existent. they are the judge and jury. passing sentences like its going out of fashion. if only people would realise how petty and unproductive this is.
rather than spurring someone to learn and improve, one would rather pick on the mistakes and pretty much try their bestest to ensure that the mistake is remembered and forever reminded.
