Both the words chronic and permanent seem to mean forever at a first glance. The dictionary defines them not as forever per se, but kind of, sort of, basically. This is counter-intuitive, but like many counter-intuitive things, they make sense the more you think about them. A permanent resident is one with no plans to change that status, and as long as they do not change, they are functionally different from forever. A chronic illness can go away, but probably won’t. It is incurable. You understand.
This is just to say,
I said I would love you forever. I lied.
So you meant you loved chronically?
Yeah, the narrator wrote love with permanent marker on skin, you see.
