We are all desperate, of course, to marry the right person. But none of us ever quite does. The fault isn't entirely our own; it has to do with the devilish truth that anyone we're liable to meet is going to be rather wrong, in some fascinating way or another, because this is simply what all humans happen to be - including, sadly, ourselves. Yet - as this darkly encouraging and witty essay proposes - we don't need perfection to be happy. So long as we enter our relationships in the right spirit, we have every chance of coping well enough with, and even delighting in, the inevitable and distinctive wrongness that lies in ourselves and our beloveds.
