spilt water is hard to save.
being right, is the most important thing that there is. sometimes people argue just cos they want to be right when they are not. they think they win in the process.. but in reality they cant but escalate the conflict further and just reveal their illogical thinking habits.
not long ago, i talked with someone... and he just exploded for no reason. its good to back off at those times when people come at you for no apparent reason other than their crooked logic.
