"What Rodríguez remembers of his time living wild is that it was 'glorious.'"

"When he was found by the police and brought down from the mountains, an untroubled, simple adolescence among animals and birds was cruelly cut short. He had always found it hard to relate to humans, who were baffled by his ignorance and infuriated by his inability to communicate.... [Marcos Rodríguez Pantoja] told me he was still a child, only six or seven, the first time he encountered wolves. He was looking for shelter from a storm when he stumbled across a den. Not knowing any better, he entered the cave and fell asleep with the pups. The she-wolf had been out hunting, and when she returned with food, she growled and snarled at the boy. He thought the wolf was going to attack him, he says, but she let him take a piece of the meat instead. Wolves are not the only animals he lived among: he says he made friends with foxes and snakes, and that his enemy was the wild boar. He says he spoke to them all in a mix of grunts, howls and half-remembered words: 'I couldn’t tell you what language it was, but I did speak.'...  'When a person talks, they might say one thing but mean another. Animals don’t do that,' Rodríguez told me.... José España, a biologist and specialist in wolf behaviour, who knows Rodríguez.. says... 'When [Rodríguez] says the fox laughed at him, or that he had to tell off the snake, he gives us a version of the true reality, what he believes happened – or how, at least, he explained the reality to himself,' Janer told me. 'Marcos’s mind was desperate for social acceptance,' he told me, 'so instead of understanding the animals’ presence as incentivised by the food, he thought they were trying to make friends.'"
