This always makes my day, we take so many things for granted in the USA, but the truth is, there are knives that need to be sharpened.
Man Sharpening Knives Right in Front of Restaurant on Lake Atitlan
The man does not know how to make a knife super sharp, but it is big mis-understanding of people, truly the developing world, the normal 200 does not have a fully developed knowledge of best practices. They need to know what Americans knew as common knowledge 50 years ago. Yet, we send in the social workers to teach them how to develop... LOL.
