Wandering through the crowded streets of London in the morning thinking about how odd it is that people get annoyed over little silly things such as losing their keys. As I daydream a man looks right at me with an angry look on his face. I think it's just the way his face was built. You know, to look angry. He looked both angry and a bit confused. I burst out laughing and tried to disguise it as a cough. The poor bloke looked even more confused. I carried on walking genuinely shocked that I'd laughed in a stranger's face. I've no idea what he was annoyed about or even why his crumpled angry face made me laugh so much.
