Hamlet. Madam, how like you this play?
Queen. The lady doth protest too much, methinks.
Every time someone answers a simple question with an overly long and self-justifying response, this exchange runs through my head.
"Over-explaining" is a common result when people are reluctant to admit they don't know something, or trying (too) hard not to accept responsibility for a mistake. I'm sure I've been guilty of this myself -- but the right answer is (almost) always to put down your shovel and stop digging.
P.S. -- I'm not much of a bible scholar, but the spirit of this is similar to Proverbs 28:
"The wicked flee when no man pursueth: but the righteous are bold as a lion."Next time you're tempted to dig yourself out of a hole with words -- to flee when no man pursues -- remember the words of the bard and shut your mouth.
