So, I sat down next to this woman on the train. She says, ‘just to warn you, I have head lice.’ So I get up immediately, and I move about 6 feet away on a train that’s about to be full of people. At the next stop I paid attention to her warning a guy that sat down next to her. She smiled at him and said hi, and he said hi back. I watched as she eyed him up and down : she didn’t warn him, so I did. I said to him, ‘she warned me as I sat down next to her at the previous stop that she has head lice, just so that you know.’ He said thanks and he got up immediately. She said ‘ why did you tell him that?’ I said so I could warn him like you warned me, and for as long as I’m on this train, I’ll help warn every male passenger that sits down, just in case you don’t.” She made a big sigh and she got off at the next stop.
