“A person’s eyes never lie,” a friend said to me while we were having a quick coffee in a bar on the outskirts of town. She was convinced that the expressiveness in a person’s eyes would always give them away. I saw no reason to contradict her. I left the bar alone and after thinking about what she’d said, I couldn’t help looking at the eyes of people walking past me in the street. I wanted to see if I could guess if a person was bitter, humble, arrogant or vulnerable. The experiment came to an end when a child walked past. I couldn’t see a thing in his eyes. It was like looking at a book that hadn’t been written yet.
