It was neglect, lots of people have routines and lots to do and remember every day.

The point is that it happens when it's NOT part of the usual routine, though. If the person involved has genuinely no idea that they're leaving a child in a car then it's not neglect... neglect is conscious. For example, leaving a child somewhere believing that "they'll be fine" without considering the danger, or simply not giving a ****. That's not the case here.

Yes... And my point is many have routines and they still remember to do things.

As I'm sure this man does 99.99% of the time. It's is a freak psychological occurrence but it happens to everyone. Absolutely everyone, to some degree. The only difference is that usually when it happens it's something minor that doesn't end in tragedy... Like accidentally putting your keys in the fridge and then having no idea what you've done with them. Or a customer of mine - drives into town every day, Parks in the same place - on a nice day decided to walk in, then an hour later he was in a panic convinced that his car had been stolen... when he hadn't brought it in the first place.
