I only wear sunglasses when I want to secretly watch people. Kind of like a spy or an assassin. You know. If I'm walking down the street and I want to watch someone walking ahead of me, I don't want to be seen. I want them to think that I'm looking across the street and not at them. Or watch people through their windows. That's always fun. But I don't usually wear sunglasses for anything other than spying. If I did, they would be black to shade my eyes. But when I wear sunglasses, I must wear a hat and a long trench coat.
