I'm reminded of a scene in The Dangerous Lives of Altar Boys, with Kieran Culkin and Emile Hirsch. (Great movie, btw.) Minor spoilers:
The boys are riding their bicycles along a country road, and happen upon a dog that's been struck by a passing vehicle, and is dying. Hirsch's character, Francis, says (paraphrased), "Someone needs to come for it. They need to do something." Tim, played by Culkin, responds, "There is no 'they'. We are they."
I trust the scene's relevance isn't too obscure.
What always stuck with me was the end: "No one was coming for this dog, I hope you realize that. Nobody around here, no one who passed it, not even the guy who hit it. I hope you realize that. Don't you ever tell me to get real. I know what fucking real is, okay?"
