You have no items in your parents home that reminds you of something you did as a child? Nothing?
If I see something useful that also reminds me of my parents or my childhood, all the better. But it has to be something that's integrated into my life, not something that I'm attaching to my life because I'm afraid to give anything up.
edit: I do have to say that there might be a subtext in the article that I agree with. The useless stuff that your kids will have to deal with after you die is probably also useless to you now, so you should deal with it now.
I do not have the space to keep a lot of stuff.
my parents got divorced and my mom abandoned everything and everyone
The cloud, my backups, are really my only physical "treasure".
