As usual, nothing beats the comfort & familiarity of hanging out with old friends. Don't have to go through the hassle of getting to know the person & impressing anyone, as you know and they know all that is to know. Well, though, you've to spend some time filling in each other with the latest bits from each side.
But one thing I find hard doing is trying to get my family & friends to know what life is like for me on the other fence, without them. It's hard for anyone to understand unless they're in the same boat as you. I guess I could try if I am a good storyteller, but sadly not. Most of the time when people ask me how's life in Japan, I just keep repeating the same old things like, "oh, it's so hot or so cold", or "the new apartment is so small" blah blah blah. I can only really go into detail with someone who has been through the same situation as me. Just like the other night, I met up with one Singaporean ex-JET who has also moved to Tokyo for her new job for a meet-up. We went through the same hell & problems of finding a new job, apartment & the fear of having to leave our boyfriends here if we couldn't get a job. It was amazing that we went through the same emotions of going through those processes! It was like, "Did you ......too?", "Yeah! I felt ...." and "Yah, me too!". It felt quite good to laugh at those emotions now, now that they're over.
Hmm, I've detracted a lot. Just as I think that having new friends who share the same experiences as you is important, old friends are equally as important, or even more, as they are the anchor in your life that never goes away (unless you decide to dock somewhere else for good). They may not know exactly what you're feeling now, but they know what you're like. New friends are like other boats that go sailing on the same adventures with you, but eventually, they leave to go back to where they're from.
