“ Memories can be so fucking weird.” And painful too. So sorry your dad abused you. And your mum and the bathroom thing, well I know a generation or three ago, more women accompanied each other to the lav. I guess it’s an inbuilt safety in numbers thing. But, it could have been something weirder.
I meditated and went into a couple of my own memories a few years back and saw and heard myself acting as I wish I had then. I felt like a tiger when I’d finished! No longer at the mercy of unpleasant recollections.
