It was addressed to my children, in my handwriting. And it said "in case I'm not around at Christmastime 2013."
Wow. So glad you're free from that. I wrote "death letter" to my older son while I was in Iraq in case I didn't come home- he was 5 at the time. It's a scary feeling to imagine not being there for your kids. I threw the letter away, but I've never forgotten it.
