I’m not sure what this is — some National Geographic thing? — but it’s fascinating. The short clip follows a group of young Sudanese men who move to the United States and remark on the cultural differences they observe.
Their reaction to the food and the characterization of the US as unfriendly are especially interesting.
Update: Several people wrote in to say that this clip is from the 2006 documentary God Grew Tired of Us. (thx, all)
