. If an adult'd been standing in close proximity, this wouldnt've happened.
Um, why? What could they have done? Watched him smack into the ornament? I suppose they could've caught him, but that would only have been possible had he bounced off pretty near them. And when you consider it, most people when supervising such stuff usually sit down etc. so it doesn't actually have much preventive value.
The sheer fact of the matter - that someone seriously needs to tell the Perrys - is that stuff like this just happens. It always has, and always will, and it's incredibly unfortunate. But kids mess around, and at some point someone ends up getting hurt.
Adults should obviously be around to enhance 'reaction time' and treating the child in question, but really there isn't much they can do to prevent it.
The whole idea of bringing compensation and things into events like this is just stupid and it doesn't really help anyone.
