How on earth am I supposed to get my point across to someone who absolutely refuses to listen? Not only does said person refuse to listen because of incapability, but they just don't want to hear it, ever, at all.
The irony? Said person put themselves in this situation, and it's eating away at me, because I try so hard to be gentle, and kind, and nice about it, but I can't. There's my incapability - once I lose patience for someone, for whatever reason, it's a rarity that it returns. I have to see some kind of significant behavioral modification for that sort of thing.
But said person acts exactly the same way, no matter how many times I explain, or how pleasant I force myself to be in such situations. And I lose it, every time. GRAH!
