Bro,we do not believe in these `untouchable’ things.What I had heard from my grand parents is that,they had unheard of such things.
But in Punjab,Hindus paid a heavy price by following this system.They had alienated themselves from the Muslim community with this practise(Hindus would never touch or drink from the utensils used by Muslims).
Bhai, Are your Hindu neighbours originally from Sindh or migrated from elsewhere?
