When I first heard someone make reference to the stereotypically feminine complaint of "oh, I can't do that, I'd break a nail", I imagined that the person saying that was concerned about the nail completely breaking off down the middle. Having at one point trimmed off my own nail a bit too close to the flesh, this sounded like an excruciatingly painful thing to happen and I couldn't understand why the complaint was treated with such derision.
