Indian textbooks aren't particulary famous for being progressive. Right from the merits of dowry to blaming women for rising unemployment, there are many things wrong with the education system and what impressionable students are taught.
However, this chapter from an ICSE textbook is a delightful exception. The chapter titled 'Changing Roles of Girls and Boys' talks about the perception we have of how a girl or boy should look. It challenges this perception and argues that people can dress or look however they wish to, without any gender roles coming in the way.
