There was a time when Hindus would be invited to the houses of the Muslims on the day of Eid to eat Muslim foods together. Hindu children would wait outside the Eidgah to meet and embrace their Muslim friends after the Prayer.
Similarly, Hindus would send their homemade sweets to the nearby Muslim houses during Durga Puja. Muslim boys would go to Hindu Puja Mandap to watch the Hindu performance and would accept and eat the sweets.
Should it be considered bad for the community when both people live side by side for centuries? For the Talibanic people, it is a big issue, though!!
