Meeting during recess or after school classmate, who is angry since yesterday (did not give to write the math problem), you take his leg, never thinking that it could lead to severe injury, even a fracture, concussion. It happens. But now he's just stumbling and grasping the lapels of your jacket, shaking you as it should. And it turns out that the advantage, alas, not yours, and on his side. The conflict ends with a bruise on one side and two scratches on the other. And all because you failed to hide his hostility, did not appreciate critically their behavior, do not understand the true intentions of a school friend. Why should he give you his notebook? It is possible, even likely, he had on this account their views, and he much rather would explain you, rightly believing that cheating is pointless, the real knowledge it will bring. You yourself seemed to be a fighter for justice, a sort of stronghold of the principles of the partnership. And really? In fact showed himself to be lazy, quarrelsome, cocky, selfish, least of all thinking about justice, comrades. And well, if you just will be able to get rid of these disadvantages, win a harshness, intolerance, selfishness, which can serve you the best service in future life: in the army, the workplace. Not to mention the fact that a person with such traits can hardly find a place in a space ship.
