Very interesting and well written thoughts. I've never been to an estate sale and after reading your thoughts, I don't know if I would.
I find the same thoughts about 'stuff' in my house and who would handle it. I've said to 2 friends that I'm leaving them in charge - they think I'm joking - but I'm not.
I've been trying to identify my sewing things (i.e. what goes with which machine...what's expensive...etc.)
