I only go home once a year on Eid to see my family in Hazara. I live in Karachi and supply water to shop owners on Burns Road in these gallons. If the shop is on the ground floor I charge Rs.30 for 2 cans of water. If I have to take it up the stairs I charge Rs.50. But the money I earn is not enough to send my children to school. They deserve to go to school but I am helpless.
