I’m trying to think of an instance when this could be a positive thing to say. Obviously, here, it is really shitty. Here, the priest is like, wrap it up! That’s it! My time’s up. Give me my funeral money, throw some dirt over the dead woman and let’s call this thing over.
But… you could say it when you were done with a piece of art – like a painting or the final draft of a play. I’m working on a draft of a play right now and I have to submit the changes to this thing tomorrow and at a certain point, despite wanting to work a great deal more on it, I will have to declare that no more be done.
