Today I got a Google news notification for a BBC article about the country
where people go to bars to drink milk -- Rwanda. Although closer reading of the article suggests that those "bars" are more like
coffee shops.
Anyway the article also provided some useful phrases in Kinyarwanda (the language spoken in Rwanda):
In Rwanda, when you want to wish someone well, you say, "gira inka" (may you have a cow) or "amashyo" (have thousands of cows), and... when you want to express profound gratitude, you say, "nguhaye inka" (I give you a cow).
