It's funny you ask this. My mom died a few years ago and I have been going through her stuff. She has things from her life, like high school projects, yearbooks, etc. She has a lot of stuff from my grandmother, like her high school diploma. And I have furniture from my great grandmother and grandmother. And then all my mom's artwork.
Well it has kinda made me feel mortality. I don't have kids and I'm wondering what happens to all my crap when I die. Who get's all the family photos and carries on memories? I have cousins that have kids and I am going to make sure they get all the family stuff and pass the photos on.
Oddly I've had a life of pursuing my goals and having adventures, and children wasn't a priority. And I have a sizable trust fund that I'm not going to spend before I die, so I have to think about what happens to that.
I guess I could marry a gold digger who has kids, but little more than ungrateful brats who will squander the money ...
