Now that woman in my mind DEFINATELY lacked in parenting skills, she lets a complete stranger just walk away with her kid.. accepting a car ride with someone she doesn't know etc etc etc.... Want to talk about someone who wasn't thinking and put their child at risk, that woman definately did.
I think this whole thing is also about not thinking and putting their child at risk. Not checking on your children for close to 12 hours straight (assuming the parents' story is true), even after the alarms were tripped and the door was open is DEFINITELY NOT THINKING AND NOW THEIR CHILD IS GONE! I pity them for how they are probably kicking themselves over this. If they love their children (and I'm sure they do) they're going to go through that night over and over and over in their heads and they are going to wish with all their hearts that they had done something differently.
I'll tell you one thing, if they were swingers (and I don't doubt it, seeing as how they won't deny it), I think that their swinging days are now over.
