A passive aggressive child is one who ignores responsibilities like doing homework, daily chores,Etc. They instead of listening to you tend to be silent. They work just the opposite way we want them to behave. It is very difficult for any parent to tackle these children. Whenever you question them, they remain silent or give you nothing more than a scary look.
But time can't wait for them. They have to learn, do their homework. Otherwise,the teacher will rebuke him for something he is capable of but not willing to do.
By passive aggression, the children tend to gain control over their parents. They use this weapon to make you believe that he is not worth of your expectations. He doesn't have the potential to grow up to the targets you have set for him. This is a trick commonly used by children to make their parents work for them.
