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!
