Well to me, I dont think anybody whao travels or stay abroad seems a special and unique person.
Apart from the fact that travelling is part of education and an eye opener to so many things, some people at home are more current than most who came abroad.  Some people are here abroad, there is nothing to show for their travelling, some dont want to come home because of failure, so what is the specialty and unique in them?  Abroad is just a place to look for greener pastures, if our Country could give us the necessary things we need, there is no even the need of travelling.
Those who think they are special when they come home are the noise makers here abroad.
We are all the same people and we should not treat them as special people, but welcome them for the time we have missed them, that's all.
