When I learning to drive, my mom told me it was against the law to drive in bare feet.
I duly informed others when they attempted to drive bare-footed of this obscure, little known law.
Ten years later, dozens of people informed, I found out it was my "mother's law" not a traffic violation at all!
I often wonder how many people passed what I said along to others and just how many are out there are wandering around obeying "mom's law." haha
