Lost Flirt Finder - Can't get You out of My Mind ! Where are You ?

I was waiting for a friend, when you came down the stairs talking to a friend. It looked to me like you were heading home from university or work. After that we looked at each other long time, when you were in the Metro. You smiled an waved shortly before the trains left the station. You have short brown hair and tooked some kind of documents with you. I was wearing a green outdoor jacket, have brown hair and wear binoculars.
