And most of the people I often hear explaining themselves are doing it in front of somebody who does not even care about them or could not care less about the thing they are explaining. Even if they listen to the explanation, it is often useless because they end up either not believing or simply still not caring. It is true, explaining yourself is most often a waste of time.
You know there is this unbearable level of emotion one would be, it feels heavy in the heart that what can only make it an ease is explaining yourself out and all grievances or weaknesses will be normalized in orderliness.
As well, there are people who don't deserve your explanatory because they have nothing good to offer and if time not taking, you are probably explaining yourself out to the wrong person giving it chances to eat you down.
