It is VITAL that you summon some compassion and understanding for your wife and all that she has endured and managed to accomplish in spite of it
And don't forget admiration. She probably craves that even more than she does compassion or understanding. Most people assume that she should never have had the chance to be anything but a useless child, but she's proud of having been something more (even if the person that bailed out and gave her that chance did something reprehensible) and she'd love it if you noticed and admired that and the skills, strength, and patience she gained from it.
a fine and enviable madness, this delusion that all questions have answers, and nothing is beyond the reach of a strong left arm.
