When I was a kid my mother made me hold on to the shopping cart as she pushed it along, so I would not wander off. This was so ingrained that to this very day (I am now 38) I still hold on to the cart when my wife and I are shopping. I am not even aware that I am doing it, and when I catch myself it always makes me laugh.
