Our collection of perceptions in the world are all we have.
All we can do if look down on someone that chooses to use their time in such a way. Well, there are ways to see them equally and take note of other merits, but the exhaustion involved compared to not having to let every comment slide or explain something slower reaches a breaking point. It is always, within a wide reason, better to forgive and forget. The idea is noble.
The utopia of complete goodness... so many people have so many different ideas of goodness, though.
It would have to happen singularly, within oneself, and with the recognition of the notion of evil or a toned down form... like mischieve. If there were no evil there would be nothing with which we could compare good. You would at the very least have to have an idea of evil in the past. Our world is driven by duality and it seems our purpose to bounce back and forth between notions. Without light there is no shadow and so light loses its brilliance. When all is known there is no suspiscion and so no place for the creative mind to nurture itself.
Outside of isolation it may not be possible to live in true goodness for a long time. There is a great misocaineia in the world that draws a line.
The animal/child mentality of innocence would best describe the notion of no rights and a like amount of wrongs.
Rudeness stemming from sheer ignorance will always be misinterpreted as long as people have a notion of themselves, and while the ignorant continue to be so. When a child begins to learn those concepts his imagination is taking hold. Our creative selves make humans what we are (aside from the physical stuff). Part of the reason for the existence of awareness is the contrast between right and wrong, day and night, male and female (not sequencially respective, ladies).
Hatred is a powerful force.
It always amazes me when bright people succumb to the idiocy of spats. I berate myself when I do it. Not to sound elitist (unless it's too late) but there are so many better things to be gained even through trying to study that person and attempting to find out why they are the way they are or trying to help them to see something despite their manners.
Then again (and I might say there is ALWAYS "then again"), old skool relaxation and easiness between good friends can quickly turn testy, but as Bebelina said, if it's understood that someone's joking or amends are soon made, there isn't so much damage. Oh well.
