In Italy where of course the story is headline news, including having the mother (who is 8 mths pregnant) reading out a statement saying what a wonderful father her husband is and how she'll never blame him.
The child's organs have been donated and (rather bizarrely and unnecessarily IMO) the parents of the recipients are also all over the television giving opinions.
I agree with those who say until we've been in that situation we don't know how we'd react, your gut reaction as a parent who has never done it, is that you would never do it, and I agree that what seems odd to me is that he forgot for so long. But as people have said, maybe in his own mind he had left the child at preschool. I do find it odd that she was in a busy looking carpark, where surely during the day, people would have been coming and going. Unfortunately, it's a bit the nature of the beast in Italy that people Do Not Get Involved, but I'm also fairly sure that where a screaming child was concerned someone would have done something if they'd seen or heard her?
I don't know how the mother can find it in herself, accident or not, to forgive him. (she says she has nothing to forgive) but again, until it happens to you I don't suppose you know how you'd act. I would never be able to look at him again, but that just makes the mother in this case a better person than me.
