To Raju Das, Before pointing out anybody or giving advice to anybody just think what are you. From where did you learn English ? This platform is to be used for solving our problems. I have seen many comments made by Mr. Utpal Mukherjee and I feel he (Mr. Mukherjee) has a positive attitude to help others. What is your problem? It will be better if you oil your own machine. Understood ? I congratulate Mr. Mukherjee for a heavy slap on your face with a very descent language.
