My wife and I use the pinky promise as a sacred oath and sometimes an investigative tool.

If we’re not okay, or we’re worried the other is putting on a face to get through a moment without being honest, the pinky is used as a “I won’t ask again, just promise me you’re alright, or will be alright, and we’re good” and that kicks off a conversation or she confirms that she’s fine and the tone is residual from another frustration.

Pinky is sacred, if my wife lied on a pinky promise, it would breach our deepest marital trust.
