I came on this forum as I knew I would be going back to the U.S at some point and really wanted to understand America and Americans from their own perspective rather than people who had not been through the same experiences or even been there! There was also a complete stranger who was more than happy to help me with all the Immigration paperwork at a time I was quite flustered with it and going through a major upheaval in my personal life.
I married an American, but I didn't marry the country, or even like it the first time and I had trouble understanding why I was considered a snooty english chick over there when in fact I was actually just reserved, typically British and took my time to get to know people.
I have stayed because the Americans here are the ones I wish I had met in America! That might sound insulting, I truly hope it is not, but the guys here have a wonderful mix of American/British perspective and it makes for very interesting discussions. I love hearing everyone's view, expats share a very unique set of circumstances and I have found are very honest and open in their exchanges. I have also made some very good friends (albeit virtual friends) and I stay because not only do I keep learning, but because I might be able to offer up some help when needed.
Therefore, I think this forum/expat community is an incredible resource if used appropriately and this one in particular is well run, well moderated, free of charge with members who mostly respond with care,consideration and sometimes outstanding generosity and I just wish the people that choose to be argumentative or derisive for the sake of it would remember that.
