Tolerance

There is a saying, "gorom vaat e biral bejar, uchit kothay bondhu bejar". If you offer a cat it won't like steaming hot rice, it will sniff and express dissatisfaction and move away. And when you say the righteous words to a friend that goes against his stand, he is likely to dislike those words and your friendship may be ruined, it depends on his power to take the truth because true words are intolerable.
I think this adage is applicable to organizations, team work or even in case of politics. Even good friends split when there are differences in opinions and conflict of interest. Everyone is concerned with their own gains. People hardly agree on issues unanimously at the same time. Thus it creates a conflict and it takes time in decision making. Whenever a group of people work for a specific goal there are plenty of opinions and views.
One's opinion may not match with others or may go against them. But a conflict does not have to arise all the time. People have to be tolerant .
