An unexpected discovery can change people's lives. Ferran Mascaró and Gemma Vilanova were at the beach in Tamariu in the summer of 2015 when their son, Josep, ran off. Josep was born with autism and, from a young age, would run away when he was in crowded places. Sometimes they spent hours looking for him and had to call the police. Other times they would catch him in time and the boy would get upset. But that time on the sand in Tamariu, Ferran started running alongside his son. Instead of grabbing him, he kept running, improvising a game where they played tag. The father saw that, if they ran together, Josep smiled. And so they kept going. "We spent about 8 km running, heading along the coastal path. When we returned, Gemma was worried, as is normal, but we returned with a smile," he recalls.
