I was in Kathmandu recently after a long break. The biggest change that you will notice is the people. 15 years ago the demographics used to be less diverse and now it is diverse to the extent it has changed the whole experience. You see a lot of madhesi and pahadi faces no offence to the madhesi and pahadi community. The place feels different and not the same. With time, even friends have changed their priorities to be more into earning and saving money. All in all it is always a fun experience and you realize how much you have missed by living in a foreign land.
