It is not funny to me; it is sad that so much of that happens in the world.
The kids are too young to understand what they are fighting about.
This shows a typical dysfunctional family. The woman (the mother I assume) causes the kids to fight then criticizes them for fighting. The boy has plenty of reasons for being frustrated; his mother is a jerk.
The mother should be understanding and supportive; she should support the boy's feeling that he did not want to marry the girl. She should explain to the girl what is meant. She needs to explain to the girl that marriage happens by two people in love. She should use this as an opportunity to explain good behavior, not cause bad behavior.
Oh, but perhaps I misunderstand something. Are marriages in India always arranged marriages?
The people of India are good people. I assume that kids in India don't fight like they do in this video, so I can understand that it is humorous for some people. It is not funny for me; for me, it is sad. Because I see too many people fighting like that, and they are not funny. It is dysfunctional behavior such as that that causes bad things to happen in the world.
Thinking is a feeling; pleasant for some and unpleasant for others.
