Diwali started on Monday — it’s actually a week-long festival. So everyone was shopping “on time”!
Last year, I went to the one sweet shop in Jackson heights that has a special spread at Diwali (I think they fly in halwais / sweet makers from India because the sweets taste different / correct vs the rest of the year) — I don’t generally do queues, but this one was festive and everyone was in a celebratory mood, including the many non-Indians on line!
