One morning after yoga, there was a pounding at the door. Mrs. Upinthevalley ventured out to see what the woman wanted. Agua! Agua, por favor! She was holding a full water bottle in her hand, which created some confusion. There was a brief tete-a-tete, then she shuffled on her way. She knocked on every door on the block, asking for water, while noshing on a bag of churros. No one knew who she was.
