A Pakistani or Chinese citizen may not be cognisant of the amiability between the two Bengali speaking areas. The national anthem of both the countries has been penned down by the Nobel laureate Rabindranath Tagore, no Bengali would be committing a heresy if he were to sing 'Amar sonar bangla', Bangladeshi anthem in West Bengal atleast in my view. Not only their anthem, their army's marching song 'Chol chol chol' by Kobi Nazrul is dear to most Indian Bengalis. Not every relation can be quantified in shades of black and white, dear Han friend.
