When I was studying overseas, I skyped with my family every Sunday for an hour and we would talk about everything that is happening around us. When I was back once or twice a year during vacation, friends and family were also very enthusiastic to feed me with local dishes and catch up. But once I come back for good, things changed. Friends were no longer enthusiastic to meet up, since there is a lot of time anyway. There was also less interaction in the family. Perhaps being away for a long time sometimes is better?
