So yesterday my brother (13 yo) and other boys of the classroom were sent to the library by the science teacher as soon as she entered the class. Why? Because today was the day the chapter "Age of Adolescence and Reproduction" was started. clap clap clap.
After the class with girls was over, the boys were called back and told "Khud chapter padh lena kuch samajh na aye to puch lena" which translates to "study the chapter at home yourselves and ask me if any doubt arises later"
This ^ is the story of a reputed Delhi school in a posh locality.
