There are different kinds of 'ouch' inducing statements varying by degrees.
Some are mildly annoying, like a pinch, which doesn't really hurt beyond the mili-second in which it's made and then it's over.
Then there are others that are more like a slap on the wrist. Sharp, but easily forgettable.
Still others are somewhat like what I imagine acupuncture would feel like, sharp, as painful as a large number of needles being pierced into one's skin, but at the end of the day, when its-over-its-over.
And then there is the worst kind of 'ouch'. The kind that that feels like somebody kicked you, very hard, on your chest almost exactly where your heart is supposed to be. And although it feels heavy, and sort-off bruised, your heart beats faster, almost painfully fast, as few minutes pass and the 'ouch' factor just intensifies. To the point where you physically hurt in a very incomprehensible kind of way. Even when you're trying to be nonchalant about it (because-its-really-not-such-a-big-deal-and-you're-not-the-kind-of-person-to-let-such-a-little-thing-get-to-you-anyway) inside you know that it kinda IS a big deal. Because your throat is dry, swallowing is difficult and you're struggling not to think about what was just said. And even as you don't-think-about-whatever-it-is-that's-not-supposed-to-be-such-a-big-deal-but-is, a part of you realizes how very, very much you care.
