Imagine freeing yourself of all social inhibition. Feeling totally comfortable talking to just about anybody. Now couple that with an unabiding empathy for others, and that’s what it’s like to have Williams Syndrome. A rare genetic disorder afflicting one in around 7,500 kids, Williams Syndrome people are prone to being extra friendly, trusting and high on life. The downside? They lack a healthy fear of strangers, and are unable to discern a friendly face from a threatening one. ABC News reporter Chris Cuomo hung out with some of the kids and adults with the syndrome at a special summer camp and was moved by their eternal optimism and kindness. Check out the video of his trip above.
