In response to tekla's comment and some of the responses. I returned to the UK 12 months after emigrating to Australia, for a holiday. I was also a bit homesick. I caught up with my closest friends, who were all living in the same area as they had. I couldn't believe how stagnant they were, and I don't mean that rudely. However, they still drank at the same pubs, did the same things on the weekend. Eat the same food. No one had moved on. Except me, I had totally different interests, and not just due to GID. I had experience of a different culture, I was ( and still am) completely self willed, while they were totally dependent upon the group opinion.
There is never a way to back. And once you have gone forward you really don't want to.
I have to admit, with some sorrow, that I never bothered to keep in touch with them once I returned to Australia. Of course, they all wanted to visit, we made plans. Nope. Too far out of the comfort zone.
