Can't sleep. Why are people playing loud music at 12:00 AM?

Why do some people have to disturb the sleep of others? Some people have to work, students have to go to college. I don't understand why people have no empathy at all. I can understand playing music in the evening but why this late at night. So sick of us Indians being savages and uncultured. I used to hate North Indians for being like this but it seems like Axomiya people are not that far behind.
