A scene that is repeated everyday, all over the world. Five guys were watching one of their colleagues doing the work and giving him advice on how to do it. In the background you can just about see the exact same scenario taking place! They were improving the drainage in the street in Lusaka, where I lived for 5 months. They actually started well before the rainy season, an unusual example of Zambian organisational and planning skills. Before I left the rain just started and the work done did mean there were no floods.
