Let's Start from Beginning

In his childhood, boys don't care about anything. All he want is someone/something to play with. soon after, he can realize that his mother and father will love him and take care of him. But problem starts, when is starts to understand things. For example, if his father brought her daughter a new dress and don't asked for him, he will get upset and starts hating(more specific, dislike) both his father and sister. And it is obvious. It this happens to him for more time, he will think that he is bad or his father don't love him. From here real changes begins that lead him to choose wrong path.
