It was pouring with rain and Metui, tall and lean against the grey sky, stood wrapped in layers of colourful shuka cloth. He looked overwhelmed by our very British deluge. Juggling our umbrellas, we shook hands and set off to visit a local primary school.
Metui had come to the UK on a grant to learn about British teaching methods. His own school in Tanzania - the Eluwai Primary School - caters to 400 children with a staff of just seven teachers. He and his colleagues drew lots to come on a visit to the UK. Metui won.
So chance brought him to a wet schoolyard in Henley-on-Thames on a Thursday lunchtime. The school secretary showed us around, pointing out elaborate artwork by the children, lunch menus, a bank of computers and a science laboratory. An encounter with some of the children in the library finally broke through Metui's reserve. His eyes alight, he joked with them and answered their stream of questions.
