Oooh, great thread
My mother:
Was at birth of ds1 which was 24 hours of screaming, horrific butchery which I won't bore you with, but once ds1 had been revived after 7 minutes of not breathing and rushed to SCBU, and I was being wheeled screaming into theatre for emergency surgery, while haemorrhaging everywhere, Mum announced "Well, it's all over with now, so I'm off home" I was in hospital for 6 weeks. DS1 and I nearly died. Poor Mum came down with a "nerve rash".
Was at birth of ds2 which was much shorter but just as violent. Mum stayed long enough to see little ds2 in his little matinee jacket. She popped off home while the nurse was rigging up the Hartmann's solution and calling the doctor to see to my PPH.
About ds2's strawberry mark: "Well I won't deny it Greensleeves, it does change how I feel about him. The sooner he has it off the better. It is harder to love a child with a facial disfigurement, I don't like looking at it".
Told me aged 15 "I think your father might be impotent" - her evidence was that he had turned her down for sex. She had been married to somebody else for 10 years at the time..
Said "Oh children's feelings are skin-deep" about her kids/divorce
Told me "I hope you are not going to make a big THING out of this. It was nothing. He was just confused" when my stepfather ran his hand up the inside of my thigh during a Christmas board game. I was 19 and he had lived with me since I was 5. I was wearing a short skirt though 
Decided one day to be all brave and good because she was training to be a counsellor. Asked me to "talk to her" and tell her about any bad memories I had from my childhood "I never listened enough, I can take it now" she said. I chose the one about her making us pack our stuff into tea chests and dumping me and my brother in my father's front yard in the rain when I was 11, as we had never brought her anything but heartache. She sat silently and only reacted when I got to the bit where she picked us up again a few hours later and said "Greensleeves, get in the front, you are not going ANYWHERE. Greenbro - you can leave any time you like". She cried a bit and said "I would never have said anything like that to him, did I? How could I? No wonder he hates me..". She then dried her tears and said to me "Well if there is any more of it, you had better get yourself to a therapist. I've done my bit.
Must resist the urge to go on. And on...
