Currently majority of people move a new country to live for a long time.When they immigrateto another country they must to conform their local culture as well as duties.I agree that point for some reason where as after 2,3 years people have to accept new culture.So it is enthusiastic and very gripping to get more information about the new country in which you want to live. This may bring many good feelings when we repeat their duties or something else it would be amazing for us.If you follow all traditions such as wearing traditional costumes or eating local food in this case local local residents will be more polite to you.
Moreover I also assume that people should show their own typical traditions in their local neighbourhood. that firstly accept new culture would be difficult for immigrants.So would be impossible to get used to eat strange foods wear variety of things.Furthermore sharing your own culture is one of the actions patriotic. It shows the national pride of your country and reminds you about the origin in order to integrate but not dissolve.
To sum up,although I recognise that integrating into the local manner when living abroad is important, sharing about your own typical things is also needed.
