One major feature of the expat life is that beggars can't be choosers when it comes to home country friends. One minute you are talking with the most interesting creative mind you've met in years, and the next minute you're cornered conversationally by someone you suspect was dropped on their head as a child and annually every year since.
Perpetual travelers find more than their fair share of crackpots in their midst. Some days it feels like the motto is "Have conspiracy theory, will travel!"
On the other hand, without these types around for contrast, you'd never appreciate the warm and truly balanced souls that also line the globe. Thus, even though sometimes you wish the nutters would crawl back under whatever rock they crept out from, there is no doubt that to have the breadth of acquaintances that make the world rich you have to include them all!
