I totally agree with you about mothers and daughters talking about everthing. My own mom died when I was very young so no first hand experience there, but my daughter and i talk about every detail of everyday, that is us, what we do. My niece and sil are the same. Actually my son and i are very close and talk alot about day to day details as well, just not everyday like my daughter and i do.
I do not have that type of relationship w/my mother, never have, but I love my mother. She's a wonderful little woman

, but in no alternate universe can I see, that I'd discuss a large majority of my life, with my mother, and it goes without saying, an idea for HER to play a role in helping me murder eight people. She'd think I'd gone out of my head if I approached her with something like that. Exorcism. My father would
definitely think I'd lost my marbles. I can hear him now...
I talk/text with two of my kids almost every day, and see one of them very often. The private one, we travel together, go to concerts together, etc... but, I don't know every detail of that one's life. The other one,(The entertainer), I know far too many details of their life, I've even told them, TMI, but they have no filter. I know the good, the bad, and the ugliest. If either of them, though, even thought for a second, that it would be copacetic to approach me with aiding them, in any way, toward murdering eight people, I'd think toward having them committed.
