A teacher watches a child do his lesson at the shelter that they live at in Cairo November 14, 2007. The children that are taken in are often children of Egypt's rural poor or from families living in shantytowns on the outskirts of Cairo. They may sleep on the pavement or in public gardens, face a constant threat of rape, and sniff glue to dull the pain and numb the cold.
