If something happens to me, I want my family to go through all my toots (and Lrrr's, too) to see who I really was. These are curated versions of me that are shamelessly batting at the dopamine button, but it's probably the most coherent (lol) corpus of my thoughts, impressions, values, and ideas that I'll ever produce.
I thought at first you said 'tools', and I was feeling pretty positive about somebody in your house knowing your hobbies well enough to be able to determine your inner personality from the objects you held in your leisure time.
