The subway seems to be a place where such instants often occur, as it is a kind of crossroads for people from all walks of life. People go outside of their usual cirles, step off of their usual paths, and their lives intersect with others, even if it is just for the time it takes to go from Centralen to Hötorget.
Today a dark haired guy caught my eye and smiled to himself. At first I thought I had imagined it, but then he looked my way again, and tried to hide his smile by bringing his hand up to his mouth. I couldn't help but smile back. He flashed me a third and final grin as he exited the train.
How can something like that not make your day?
