I left work and walked to the Central Square T stop. In the train car, there was a lady. Leather coat. She was working on something with her PDA. She was focused on her PDA. I was standing right next to her. She never looked up. The thing is that she was no stranger. I knew her. She seemed focused, and I was afraid to bother her. She's been through a bit. And yet, I was sitting right in front of her. She looked up. She looked across. She looked down. She looked everywhere except in front of her as if to avoid eye contact.
