Moving to another part of the world can be exciting! It can also hold some frustration. When you experience a new culture – a good advice is to just take it all in. Try to leave interpretation and judgment behind for a while, until you learn more about the rules, norms and values. It will save you some emotional rides. I know it sounds easier said than done, but from the top of my head I can think of situations where I have felt indignation and later learnt that there was no such intent behind. It was just a matter of cultural difference.
This is not only valid for expatriation but for all encounters with a, to us, new culture.
