Remember Stuff White People Like? Well, now there's a website called Stuff Expat Aid Workers Like. I really liked this one:
#17-Pretending not to see each other
When I see other foreigners in Ramallah or Nablus, or even Tubas once (!!) it's a mix between "sweet, Palestine is getting hip" and "I wonder if they can tell that I've been here longer. Look at me blending in!"
That was a fun find.
