boycott

whenever i ask r to do his homework, he'll start crying. whenever i ask him to look at his book and read nicely, he'll start blaming the book and me, he's always right, but others wrong. Because of his lazy attitude, i really doesn't like him much, sometimes with scolding, and sometimes by forcing.
kq saw how i treat him; and he know that boy is not a good boy, so he starts acting like he's angry to him, and boycott him, he doesn't play with him nor share his toys with him, and he scold him like giving lesson to him.
r cries again.
