My mother was a hard-line, no prisoners taken, disciplinarian. Lies were never tolerated, unless of course my other was the one telling the lie.
As a child, my mother maintained an invisible "lie jar" on top of our refrigerator. Whenever my mother assumed that I was lying, she would point to the "lie jar" and warn me that "the top is about to pop off and when it does...."
Her implication was quite clear. Switches would fly and welts would appear. The reality of course was that my mother's "lie jar" never over-flowed and I grew up to be a reasonably honest person desite the fact that my mother's ability to not lie was at a high premium.
