The Walled Old City of Sana, a U.N. World Heritage site with its mud-brick buildings adorned with geometric shapes, was bustling with coffee shops at night and vendors by day. Walking through its streets with a Yemeni friend, we came upon four bearded, elderly Yemeni men — traditional daggers tucked into their belts — discussing a poster taped to a stone wall urging “fathers and mothers” to send their girls to school. When I asked what they thought of that idea, the oldest said he was “ready to give up part of a meal each day so that my girls can learn to read.” Moreover, he added, the poster had just fallen down and he had just taped it back up for others to see. Not what I expected.
