Only a few days after Christmas, my sister, who was 8 months pregnant, died very suddenly and with no warning.
I missed my last chance to see her alive, and I wound up spending a month staying with my parents anyway immediately after that, trying to help them manage.
With the information I had when I made the decision, I still think it was the right one, and I'm reasonably sure I would make it again with the same amount of information.
But I'll always wish I had made it differently anyway.
