LOL!! I said "pulling" which implies REPEATED activity. I said "banging" which also implies repeated movement. Repeated activity is much more noticable at a glance than a single activity.
The article pointedly did not say that the child was climbing on the mirror. Only that he had stepped on it.
Personally, if I had a store that children frequent I'd hope my mirrors were more securely attached.
Certainly, it is possible that the child was messing with that mirror for 5 whole minutes without the mother looking at him once. I suppose I could assume that she was a horrible mother, but that assumption would be no more valid than my previous one.
Nice that you can laugh about it. And that's some fancy dancing you're doing.
