Four days before Diwali, the stretch of L.J. Road outside Citylight Cinema in Mahim West stays bright long after the shops around it pull down their shutters. hexagon-shaped lanterns in pink, saffron and green hang in rows from bamboo poles, their paper tails moving in the evening breeze.Families from Andheri, Bandra and Thane walk the lane slowly, holding two lanterns side by side before they pick one.
