Nightime Smoke

Sometimes, at night, I stick my head out of the window and I smoke a cigarette, and I think; that's it, that's my time limit, until that cigarette burns out. And I watch the people walking past and I wonder about them; where they're coming from, where they're going to, what they're going to do in their life, what greatness will come from them?
And I think, if one person notices me I'll be ok. If one person sees me there then it will be alright. But if they don't, if no one looks… Well then I'm invisible already… I'm already gone.
