what a nice polite reply! Sorry that i feel differently to you about stuff, but really no need to get personal just because i do is there? Can i just point out that far from being thick, the explanation i put forward was in fact endorsed by the person in this post who seems most qualified to answer, an ex policeman?
I don't happen to think you have to thank people for their answers - surely the reason they come here and answer questions isnt to be thanked, but to derive some satisfaction from answering (selfish, the lot of us i say, just coming here for all that warm glow when you get the answer right!)
and mycatis, i do realise that babies could die in hot cars, hence the suggestion to break the window if she was that concerned ...
