This must be one of the most pollution free Deepavali in Chennai. You can hardly hear any sound of fire crackers. Probably due to the stringent rules in giving licence to retail shops.
In our house we normally prepare the Deepavali sweets and snacks at home instead of buying it from shops. This year it is Murukku, Ribban Pakoda (seriously, that is what it is called), Adhirasam, Mavurundai and Baadusha.
