My sister is a Buddhist and we were raised Unitarian. She says she's a Buddhist Unitarian. Anyway, she spends most of her life inside her house, behind walls, so to speak. Much of her life reeks of PTSD, but she has never been diagnosed, to my knowledge. None the less, since I was molested by our grandfather and she shows signs of abuse, I suspect she was abused/ molested too. She just does not remember it probably. Mine was buried until I was in my mid-30s.
She is a horder and has piles and piles of stuff everywhere in her house, with small pathways between everything. When I had to visit her unexpectedly, after our father's memorial service, she could not bring herself to move any of her precious stuff in order to make room for me to eat at her table. She could not clear off a chair for me to sit at the table on! It was awful, I felt claustrophobic in her house.
Somehow, what you wrote above reminded me of all this, so I am sharing it, for whatever it is worth, even though it probably has little to do with the subject of your post I suppose. I hope you don't mind.
Please tell us more about the book!
