I had already traveled a lot ( as a tourist ) before I left Greece to come and live in Japan, when I started to make a life here, I practically had to rediscover myself. It is not so much the big things, it's the small ones : habits that I took for granted, jokes that do not sound funny, if you can ask someone's phone number... Like a very thin safety net of supporting culture I never new was there just disappeared underneath me.
I also had a fresh view of Greece , and my life before
I think traveling gives you a change of perspective difficult to grasp at home
