Sometimes we are selfish for some reasons. For example I'm selfish when coming into terms irregularities, and contrary in ideas. IDEAS?....PRINCIPLES?...These are the disciplines where one can find me making a boundary, and build a very high wall that, you can't over jump unless I need you. And if I don't need you then, do not exhaust to need me, unless of course in a given critical situation one may face nearby me, then my instinct may be awakened and told to rescue as a matter of we being humans, and social animals in significant need. My dad used to need me not sometimes, if my triats are subjugating his rules aground. What does it make, when I say, and point at the blue colour and say...this colour is blue, while my son says, it's green, yet it's visibly a blue colour, does not make my son, a son to me any longer, likewise me to my dad.
