Sorry. Just because she might be dumb, overworked, overstressed, inconsiderate, self-centered, air-headed or whatever, we have not yet got to the point that we require a means, suitability or intelligence test to become a parent.
But for you to call this person, someone you never met, basing your judgement on the level of detail in the story and calling her a “monster” makes you more deserving of the title than she is.
Where the hell do YOU get off making that judgement?
Quite amazing.
We have an innocent child dead, left in a car for hours and a mother who forgot it.
Any adult that would do such a thing, like forgetting their own child, is beneath contempt, not much lower then those who would attempt to find ways to justify their criminal act.
One may forget to lock their door, or leave their lights on, they do not forget where they last left their own child.
