One day in Shianda we passed a construction site. Many village people had gathered to build a mud hut for one of their neighbours. Even if we were just passing by, the good mood of builders made us to join (and actually to not want to leave the site). Everybody could just join and help their neighbour who cooks lunch for them in return. It was great 10 minutes of building the mud hut, because unfortunately we had to go to work after that.
Here is one video from Kakamega, Kenya, where people are building similar hut.
