I quarrelled with my brothers (twins) at home on saturday.  One of them studies in a private school and the other one is repeating his form five.  They do not know what they are doing.  They follow every word of their teachers, books and systems.  They always try to rationalize their bad acts by some game and they are satisfied with their awkward life.  I have tried to persuade them very often but have failed.  This time I had a fight as they have no voluntary spirit (they did not polish the floor).
