We moped through the gray afternoon, napping to the shush of the fountain and studying maps to prepare for some sunny day. Throughout the day, a lone figure moved around the park, sometimes contemplating the fountain from a lonely perch on a park bench. As others came and went, this boy stayed. I imagined that he’d planned to study in the library and was stuck waiting for a ride home once a parent got off work. He looked to be a teenager, but he wasn’t talking on a cell phone or listening to music, he was just sitting.
