The boy who does not speak

This is Momoudou, he is 9 years old and he is known that he does not speak. Momoudou is deaf and he lives with his family in a compound in The Gambia. He goes to a normal primary school, where his disability gives difficulties with learning. In The Gambian school nothing is written down on paper or in books. Therefore the children copy everything from the schoolboard. Due to his disability he needs more time, so when all answers are given and all children leave the class, he is still working on it. Luckily his friends are willing to help.
