The ‘classroom’ is actually a garbage dump amidst a clutch of factories by the railway track near Okhla Phase I. Sophiya and Pushpa, a tribal and a Dalit, have run the Okhla primary extension programme for nearly a year. They cleared it, set up a shack, negotiated with the cops and local politicians, handled the local goons, herded together the children and now teach over 100 of them here. Every Monday morning, the teachers inevitably find the classroom destroyed but they rebuild it and carry on.
