I can say that after three years living in the UK, I experience more culture shock when I came back here, compared to when I was in Coventry. Back then, all of my friends are not that different from me, and I don't really go outside my circle and make new friends.
But now that I am here, there is a plethora of new things that I didn't really know before. To be honest, I'd rather be myself, four years ago.
They say, facing new challenges make us think more.
But, I'd rather be a nobody...
