I think that it is actually very useful to listen to people remind us how childhood used to be. The fact is that children can be outside without needing access to the toilet every 30 minutes. So yes, reminding ourselves that we played outside all day without needing an emergency toilet break is a good thing. Listening to calm voices remind us that we all survived playing unsupervised for hours at a time should be a wake up call showing us what are own children are in danger of losing.
I genuinely believe that to consider it 'child neglect', to mention calling the police or to say it is irresponsible to leave a child playing outside of his own home in the middle of the afternoon for an hour or two shows a total loss of perspective and an inability to properly assess risk. And all of these things have been said on this thread. What possible harm could come to him - really? Yes there are horrible, horrible tragedies. The murders of Susan Maxwell, Sarah Harper and Caroline Hogg are seared into my memory, particularly Susan Maxwell's as we were the same age. April Jones' murder haunted me - I too have a 6 year old who loves to play out on her bike. I wanted to grab her close and never let her out of my sight again. But I still let her play outside because, however great my fear is, I know and keep reminding myself, that I cannot imprison her because my fear is disproportionate.
Fair enough kennyp that you wouldn't want your children left like this, but just because you wouldn't make a particular choice in parenting doesn't mean it is irresponsible of another parent to do so. Very few parents are genuinely neglectful - intentionally or unintentionally. More perhaps are thoughtless, as perhaps this lad's parents were. But I really cannot see that - in terms of his actual wellbeing - they did anything wrong.
