"She's like one of those princesses in the fairy tales who used to set fellows some task to perform - it might be scaling a mountain of glass or bringing her a hair from the beard of the Great Cham of Tartary - and then gave them the brush-off when they couldn't make the grade."
I recalled the princesses of whom he spoke, and I had always thought them rather fatheads. I mean to say, what sort of a foundation for a happy marriage is the bridegroom's ability to scale mountains of glass? A fellow probably wouldn't be called on to do that more than about once every ten years, if that.
