Reaction to Rejection?

While i was travelling to my destination, i was on a seat in a public micro-bus. A girl aged about 20 years was about to enter in the bus ,suddenly a boy came to her and started to scold her in very bad way. After he scolded her , he hit on chest of the girl.Then a boy ran away. When we complained to traffic police , he didn’t take any action to it. After some time, when locals investigated on it , the boy was the friend of girls’ brother. The boy was in love with the girl. The girl rejected the proposal of boy, and the boy performed this inhuman activity.

This is the activity which is being prevalent in our society.
