My Mom has nothing that I want, that I can think of. Of course, it's going to bea bitch to clean out her hoarder house when she's gone.
After my grandmother passed, all I took was things like scissors and pencil leads--things I use but hate to spend money on. And I got a share of her LA-area house when it sold. The money was nice. I thank her for that even though she didn't like me (or anyone else, for that matter).
