What happens to a marriage? A persistent failure of kindness, triggered at first, at least in my case, by the inequities of raising children, the sacrifices that take a woman by surprise and that she expects to be matched by her mate but that biology ensures cannot be. Anything could set me off. Any innocuous habit or slight or oversight. The way your father left the lights of the house blazing, day and night. The way he could become so distracted at work that sometimes when I called, he'd put me on hold and forget me, only remembering again when I'd hung up and called back. The way he wore his pain so privately, whistling around the house after we'd had a spat, pretending nonchalance, protecting you and your sisters from discord, hiding behind his good nature, inadvertently calling out my ill nature in the process, persisting in being optimistic, and cheerful, and affectionate, when there was clearly no call for any of that. These were the tallies I kept, the grudges I nursed. Would I have indulged myself that way if I'd fully understood the situation? I would have behaved better, I hope. I hope I would have been kinder.
