I visited the Islamabad airport today to drop my uncle. Like always, I did a lot of social observation there. I was wondering that why people see off each other emotionally at airports when they have spent such a nice and memorable time together. The logical conclusion that the cold wind and a lot of waiting helped me reach was that they weep fearing future tragedies that may have to cope with alone thousand of miles away from their loved ones. You never know who will not be alive on your next trip to Pakistan and you will only have years old memory to recall.
