I just spent an hour watching 2 sisters obsessed with " keeping a promise "! How this nonsense actually made it on Dateline is a mystery to me.. is there is a condition called reverse munchausens by proxy. ? If there wasn't before.. there is now. Ladies, people die , mothers too and sometimes not the way we would have wished.. So the sisters mutual admiration society is to be respected but if you can actually make it through this episode then you will see faux tears and badly acted presentations of grief. I am not privy to the facts of the case.. but come on, it was over 11 years ago and this obsessional behavior has to have affected the children of these sisters. I am not without compassion as I have had a homicide in my family. Ladies , let the prosecutor do his job and start healing. Enough is enough!
