Tell the truth and shame the devil.
I find myself using that phrase quite a lot. While we desire to live by that phrase, we often live contrary to it. Truth can hurt and cause strain or argument. It can be a lot uglier than a lie. It's easier to say, but a tough pill to swallow.
So many times in our lives, we have the opportunity to open our mouths and let something spill forth. It often does. We later worry that those words will travel through the cosmos, or even casual banter, to the very ears they weren't meant to reach. But it does happen occasionally. Why? Because people like to talk. People don't act as we think they will all the time. Sometimes, words become weapons. Not always a dagger thrust into someone's chest, but a grenade tossed idly by the roadside. Still, it can find its target.
Always be careful what you say. Words haunt us worse than ghosts in the host haunted house known to humankind. While ghosts fade, words ring in the ears for all of time. Sometimes, karma is listening. Sometimes those spoken about. A person need not respond to digest the vocabulary. But they often don't forget. It can happen in a random moment on a random day years after the fact. Words do not have an expiration date.
We all have the ability to be wicked or evil in deeds and spoken sounds. Most of us suppress it. But we all slip. And when that minor loose tongue wags and its voice finds the appropriate ear, unrelated things make sense, sometimes. Puzzling equations become rudimentary; simple arithmetic makes a blunder. A new reality is formed... and it's up to the possessor to decide what, if anything, to do with it.
