Cut that out already!
You have some bad habits and self-destructive behaviors, as do we all. I just don't have to like it. You know it's bad for you, you've said as much. I cannot run your life, and don't want to. You are a young adult sampling the world in all its richness. I just wish you would not drink so deeply of the poisoned cups.
You're worrying me. Please please please, be finished with that, soon.
