Each morning on the walk to work we pass through another local Tanzanian school. The children brightly dressed in purple and yellow, are working away with little brushes, home made out of palm branches, they sweep the paths around their school. The patterns on the soil following a sine curve in the sand. Leaves and some rubbish is collected into sacks which are deposited elsewhere.
Then at 7:30 the gong sounds and they rush to lessons; some stragglers running to get there on time.
