After three months Naeem had had enough. ‘We are supposed to be collecting money in enrolment fees. Instead the only people knocking on our doors are beggars! This is a Herculean task, ’ he added. ‘I can’t take any more!’

By this time the two former friends were hardly speaking to each other and had to call in local elders to mediate. My father was desperate not to give up the school so agreed to pay Naeem a return on his share of the investment. He had no idea how. Fortunately another old college friend called Hidayatullah stepped in and agreed to put up the money and take Naeem’s place. The new partners again went from door to door, telling people they had started a new kind of school. My father is so charismatic that Hidayatullah says he is the kind of person who, if invited to your house, will make friends with your friends. But while people were happy to talk to him, they preferred to send their children to established schools.

They named it the Khushal School after one of my father’s great heroes, Khushal Khan Khattak, the warrior poet from Akora just south of Swat, who tried to unify all Pashtun tribes against the Moghuls in the seventeenth century. Near the entrance they painted a motto: WE ARE COMMITTED TO BUILD FOR YOU THE CALL OF THE NEW ERA. My father also designed a shield with a famous quote from Khattak in Pashto: ‘I girt my sword in the name of Afghan honour.’ My father wanted us to be inspired by our great hero, but in a manner fit for our times – with pens, not swords. Just as Khattak had wanted the Pashtuns to unite against a foreign enemy, so we needed to unite against ignorance.
