I was in the Air Force and was stationed near Frankfurt, Germany. We lived in a leased building about 30 miles from the base and there was an American "Mayor". My wife and I asked him for recommendations on where to eat and things to see and he replied that he had lived there for four years and had never eaten or shopped downtown.
I had a co-worker there who was single and his great claim to fame was that he had never set foot outside the base.
Both of these guys hated Germany and couldn't wait to get back to the states.
I'm the opposite. My wife and I immersed ourselves in the culture. We learned enough German to get around and we shopped and ate downtown. We lived in a little German village for more than a year and no one spoke English. I loved it and would have gladly spent my whole 22 year career over there.
