 An aid. It's an aid to help him maybe stay focused. It keeps him from being distracted in his own lost thoughts. I don't know what that is about, but he certainly doesn't take notes. There's no reason for him to be holding that pen. I know what you mean. It's something to keep you focused on, you know, the task at hand. You're clicking the pen. I've heard that before. I didn't notice that the other night, though.
