This is an impression that what my friend from Mozambique has told me has done nothing to dispel. And this is coming from a (white) guy who grew up in a town in the north, not Maputo or whatnot, so it's not some cloistered angle as you get with a lot of international students, especially expats. (I actually remember when I first met him, and he told me he lived in Mozambique, I said "well you must be from Maputo", which he was not. "Then you must be from Beira," which he also was not. At that point I gave up, because that was the extent of my knowledge and I was baffled as to where in Mozambique this American guy would have lived.)
With my mind fresh from my latest thread, the first thing I thought of when I heard of your white friend from Mozambique was
this.
