FAQs (Frequently Asked Questions)

1. The People Who Used the Toilets Did Not Clean them. Discuss.

People from the slum were not allowed to use the toilets. They were just asked to clean the toilets. Chetandas told that the people of the upper caste were using the toilets but they did not want to clean the toilets by themselves because they thought that it is an inferior task. They feel that it is one of the dirty jobs. The people of the slum were called to clear up the toilets properly and perhaps also take away all the waste materials. However, the people of the slum were never allowed to enter the house of the people belonging to the upper caste. 

2.What Kind of House Do You Think Chetandas’s Grandchildren will Live in?

We assume the grandchildren of the Chetandas will live in a skyscraper or in a multi-storeyed building which will have elevators. The multi-storeyed building or the skyscraper is made up of material such as cement, steel, concrete, ceramic tiles, iron rods, bricks, etc. The windows, as well as the doors of the building, are made of glass and aluminum and wood are also used in making doors and windows.
