In all these years I have just visited Karachi, Hyderabad, Lahore, Islamabad, Rawalpindi, but not the Northern part of Pakistan due to security reasons. May be some days I will go their. I have learned about their food, culture, weathers, how they think, their believes, places, working with them, their problems, social lives, problems in society etc etc. To be honest Pakistanis are very Hospitable and bound with their culture. Black Tea with Milk (Chai) is the most used word if a visitor pays visit to their home.
