Our house feels big and empty. It sits behind an electric iron gate and it sometimes seems as if we are in what we in Pakistan call a sub-jail, a kind of luxury house arrest. At the back there is a large garden with lots of trees and a green lawn for me and my brothers to play cricket on. But there are no rooftops to play on, no children fighting with kites in the streets, no neighbours coming in to borrow a plate of rice or for us to ask for three tomatoes. We are just a wall’s distance from the next house but it feels miles away.
