[reading John Doe's journal] On the subway today, a man came up to me to start a conversation. He made small talk, a lonely man talking about the weather and other things. I tried to be pleasant and accommodating, but my head hurt from his banality. I almost didn't notice it had happened, but I suddenly threw up all over him. He was not pleased, and I couldn't stop laughing.
