Yeah this is so incredibly sad, if I had come back to my car and realised that my own preventable negligence had caused my child not just to die, but to die so needlessly, so carelessly and so awfully I’m not sure how I would cope. How could you possibly go on with that on your shoulders? It would utterly crush me…and rightly so. That parent/those parents are awful awful people. This should not be anywhere near possible.
Edit: upon reading other comments, I’ve reflected on my own comment on the parents and have slightly changed my view; personally I think the gravity of the mistake outweighs everything else they have done in life no matter how good and so my statement on the balance of things is probably true, imo. However it is not something that needed to be said and nor is it a comment on the type of person/people they were up until, and after this.
