I just saw the movie recently and only one time so far. Well, of course it's about a rockstar pink who is depressed from his father's death as a young child and the fact that his wife left him, and he has had too much dope. So, he locks himself up in a hotel room and goes crazy. But the end confuses me. I have no idea what happens to pink. The kids at the end, what does that mean? I would like for someone to please explain the end of the movie to me.
