I see this a lot in people who try to pick apart my narrative about my son's death. They start off with, "Well did you..." and eventually resort to, "Well I would have..." The fact that we did nothing wrong and that it really was just a freak thing is terrifying to them. After about a year of feeling sorry for myself because the majority of our friends had deserted us, our last remaining buddy finally sat us down and said, "Look, you guys scare everyone. You're beautiful people* in a beautiful house with a beautiful family and you play by the rules. To accept that you all did nothing wrong is to accept that the same could happen to anyone, to them." I think some people might think that about SW. They have to find fault in HER because otherwise it's accepting that bad things truly do happen to good people and some people just aren't ready for that.
*certainly not implying that I am a beautiful person. I didn't edit that comment out because not only was it a direct quote but it is comparable to SW and CW-they were/are attractive people with beautiful kids.
