"still Hassan insisted..."

Hassan can only ask Amir to read because although he is really interested in words, he is unable to read. This reveals a social issue of social status affecting the ability of Afghans to be literate. Due to the fact that Hassan is an ethnic minority, he lacks the ability to read because Hassan's fate have been settled since his birth. In addition, in Afghan tradition, Hazaras have no rights and are at a lower social class. Therefore, this quote uncovers both the Afghan cultural value of minority ethnic groups at a lower social class and the social issue of education based on ethnicity.
