I know that feeling. The first time I went overseas, I just
wished time would pass quickly, so I can be home again. I guess it
was the uncomfortable feeling of being in an unfamiliar place, with
people who speak a completely different language. I still do get
the "I wanna go home now" feeling when I go to places where people
that aren't too friendly.
Being in a new country is interesting and exciting, but sometimes,
you just wish you can go home at the end of the day and sleep in
your own bed!
