I am a stranger. I am a stranger on a street, in a city, in a country, on a world. I am a stranger. I am a word, I am a thought, I am a conscience, I am an image. I am the person you've never met. I am the person you just passed. I am the person you'll see again but won't remember. I won't remember myself. I am a stranger to myself. I am a shadow in the mirror. I am an extra on a film. I am a person in a crowd. I am a stranger. I bag your groceries at the market. I give you the ticket at the movie. I am the tenant right above you. I am the tenant right below. I am the worker who mows your lawns. I am the artist who sings your songs. I am a stranger. I am anyone who doesn't know you. I am no one when you're running late. I am everywhere when you'd like to see the painting. I am nowhere when you cry for help. I have no soul and no desires. I am just the background noise to your all-important life. I am a stranger.
