The Das family home with its little blue door mounted on a threshold is one of the many inconspicuous houses that line the main road of Lalbagan Padripara in Chandannagar. Its residents, three generations of a former joint family that now meet only on birthdays and funerals (as is the norm with former joint families), are seldom seen together. But on the second Saturday of November, when I happened to pass it by, the otherwise staid house had shed its quiet demeanour and dressed up in a cloak of decadent ‘tuni’ lights.
