When I told my roommate that I had already lived in Austria on two separate occasions, and was coming back for a third time, the first question she asked was, "Would you ever consider staying here long-term?"
It's a valid question, and one, I'll admit, I've given a lot of thought over the past year or so. Because I am getting into the meat of my twenties, and more and more of my friends are meeting people they could see themselves settling down with. And so the question of location takes on added importance.
