This past weekend, the Brit and I finally made it to the Arènes de Lutèce - a park in Paris that was once a Gallo-Roman amphitheater. There were some kids who appeared to be training for parkour and other kids played soccer in the middle of the park. There was one boy with glasses playing with a ball by himself. I felt bad that the other kids weren't including him in their game. But he'll probably grow up to start some tech company, make gazillions of euros and hire the other kids to mow his multi-acre lawn.
