I met this woman on the train a couple weeks ago, she was great and I walked her home (we got off at the same spot). Since then i have wanted to see her again but i have been catching the early train from work, and i met her on the late one. She said she might start catching the bus again, but I have no truth to this and i have not seen her recently when looking for her on the late train. I did see her in a public place, but she had a phone call and i did not want to linger, but we locked eyes. I took this as a sign to get into contact. So my question is, if i was to write her a letter saying to catch the late train and put it in her mailbox, would this be seen as creepy or should i just continue to catch the late train, hoping that one day she might decide to catch the same train as i am on. Thanks
