Sighting

I was traveling by train back to Lisbon. You were facing me and I was facing you. We kept looking at each other but neither one of us spoke any words, but our eyes connected and did all of the talking. I really wanted to say something to you and I felt you wanted to say something to me. You may have been going to work. I would love to meet you and talk to you. I am sure if you read this you will know exactly what I am talking about. Please reach out and tell me something we did so I know it is you.
