"I never come here, just because of boys," Atifa says, pointing at the door of the stall. "They're opening the door." Atifa, a sixth grader in Kabul, Afghanistan, attends a school of 650 girls. Since they study in tents in a vacant lot, the only toilets the girls have access to are on the far side of the boys' school next door. The school is one of a very few for girls in the area, so some students walk over an hour each way to get there.
