But although Parvez does not understand his son anymore he loves Ali anyway. He works long hours for Ali ( -9) and yearns for the time when they were “brothers” ( -4: “We were not father and son - we were brothers! Where has he gone?”). So Parvez decides to go out with his son ( - 15) because he desires “more than anything” ( -18) to know why his son’s behaviour has changed ( -19). By this I think Parvez wants to restore his old relationship with his son. But by Ali’s claim that he has an appointment and that he refuses to accompany his father ( -21) it becomes clear that Ali does not like his father anymore. So Parvez has to insist on his opinion that no appointment could be more important than that of a son with his father ( -22). Here even Parvez describes their relationship as father and son, which shows that their relationship has become worse and worse.
