Retro: From my photo essay on Nairobi in 2004. “I like school,” says 11-year-old Mary Akinya, smiling shyly in her Sunday best just after church in Kibera. “I like reading in Kiswahili [Swahili].” Chances are, Mary wouldn’t be attending school except that Kenya’s newly elected government introduced free primary school education in 2003. About 1.7 million children previously excluded from the system are now enrolled. “I am reading a story about a cheetah, elephant, zebra, and lion. They are fighting over who is strongest. But the zebra is the smartest and he wins.”
