Is it just the cost? or people getting wise?

Last year we could hardly hear our TV sound between 9 to 10 Diwali day. We were pissed off and turned TV off. But this year, we could hardly tell that it is Diwali day at 10:30. It was complete silence at that time.

I am sure people have burnt < 50% of what they did last year. I am not sure what is the reason. Is it just that cost of crackers went high? or people getting wise?

Anyway I am happy, less sound pollution, and less money wasted.
