"You can tell a lot about a person by their feet," he mused. "Some men come in here, smiling and laughing, shoes all clean and brushed, socks all powdered up. But when the shoes are off, their feet smell just fearsome. Those are the people that hide things. They've got bad smelling secrets and they try to hide 'em, just like they try to hide their feet."
He turned to look at me. "It never works though. Only way to stop your feet from smelling is to let them air out a bit. Could be the same thing with secrets. I don't know about that, though. I just know about shoes."
He began to look through the clutter of his workbench. "Some of these young men from the court come in, fanning their faces and moaning about the latest tragedy. But their feet are so pink and soft. You know they've never walked anywhere on their own. You know they've never really been hurt."
