How did people understand about my resign?

It is three days passing from my resign from Badakhshan, and it rapidly became public. Everyone comes and asks me why I resigned; even some of my colleagues in Kabul called me and asked me why I was leaving. My answer is very simple; I am joining a professional job. Some of colleagues in turn show that they are unhappy about my leave, and some encourage me to work in a place where I would promote more. But for me it was very interesting that how did these people understand I have resigned, and why they are so interested. It gave me a sense of proud that I have been so important person but I did not know!!!???, but letter on I was thinking maybe people didn’t like me to be here, so they are happy that I am leaving, but the way they are interacting gives the opposite thought.
