Yeah I was thinking about that this morning actually.... the other day this really smelly man got on the bus (almost empty btw) and came and sat right in front of me. I nearly choked on it. Anyway he got on this morning and I was sitting right at the back and he sat right at the front and I could still smell him. Loads of people were making not very subtle comments, so he may have picked up on it. Who knows - maybe they do know, but they hate society so much they have decided to punish it.
