Short story on untouchability

i explain like this

Explanation:

In village areas and towns, everyone knows everyone else. Each caste has its own special role and its own place to live. The brahmins (who perform priestly functions), the potters, the blacksmiths, the carpenters, the washer people, and so on — they each have their own separate place to live within the village. The untouchables, whose special role — whose hereditary duty — is to labour in the fields of others or to do other work that Hindu society considers filthy, are not allowed to live in the village at all. They must live outside the boundaries of the village proper. They are not allowed to enter temples. Not allowed to come near sources of drinking water used by other castes. Not allowed to eat sitting next to a caste Hindu or to use the same utensils. There are thousands of other such restrictions and indignities that vary from place to place. Every day in an newspaper you can read of an untouchable beaten or killed for wearing sandals, for riding a bicycle.
