Back when I was growing up, mom would always advise that, when in doubt, always use good common sense. That was truly sage advice, especially because everyone knew what common sense was... I mean, it was common. No one uses common sense anymore and, according to Voltaire, it would seem no one was using it back in the 18th century, either. So, good reason dictates common sense it isn't that common. As a matter of fact, the headstone at the top of this post would seem to be on target as it is downright rare to see anyone taking responsibility for their lack of reason and discretion.
