'In 2007 I spent three months at Project Peru’s refuge for children in Lima. I arrived in July and it was winter; the people of Lima call their city ‘Lima panza de burro’­ –Lima donkey’s belly- because of the sky: it’s low and grey over your head. The humidity pervades everything: the clothes you hang outside, the cardboard walls of the houses that become soggy and bent. There is no consistent drainage system in the shantytown around the refuge; the roads, the sand of the desert –because it’s desert- seem wet, occasionally muddy. Even dust feels heavier. '
