I think the point is that people will, sometimes, leave children unattended, wether in cars or in a garden or where ever. Rightly or wrongly, this happens and is a fact of life and nearly always there are no adverse consequences. The question is, is it right for some, however well meaning, member of the public to take on the role of 'parenting police' and admonish the parent for it. As I said in a previous post, if I caught anyone peering through my windows at my children, I would not hesitate to confrunt them about it.
