LOL! I remember an incident that happened to me many, many, many..years ago. Don't know why I remember but I do.
As a small child, no more than 5, my Grandfather used to take me to the piggly-wiggly. I was fascinated by the shopping carts..wanted to push them around with one foot on the cart, the other pushing - a lot like a skateboard.
PaPaw told me not to every time..he watched me closely, one day, he turned his head, I got the cart, began pushing it, and it flipped over on top of me.
I could have been seriously injured. No fault of piggly-wiggly, it was my grandfathers fault for taking his eyes off of a precocious child!
My incident turned out just fine. But Stores can not be held responsible for everyone's children. Unless that mirror just fell off/over of its own accord..that is another thing entirely!
Actually bright boy it could have been your fault for disobeying your grandfather. But if you honestly expect anyone to be able to keep an eagle eye on a kid 24*7 or even every second of a shopping trip (you know when your looking at things like labels, prices, and taking stuff off of shelves and putting it into a cart) you're nuts..
