But this person doesn't get it even after I've said, you were planning to leave in about an hour anyway, and I don't feel well, and if you would just go go ahead and leave now it would probably be best.
So the person didn't leave, and said a bunch more things to upset me. Not that the things said were that bad, just that this person knows me well enough to know that is the wrong thing to say to me when I am upset. And, as if the person didn't already know not to say that, I said don't say that, you know how it upsets me. The same thing was said again less than a minute later, and two or three more times before the person decided to leave.
