The good: Coming up with the absolute perfect analogy to communicate with total sense-making the thing that has been eating my brain all week. May not resolve the situation completely, but my moccasins have now been placed upon the other person's feet, and I have forced the person to take several steps in 'em, and the person cannot help but go "Oh! Ohh."
The bad: This happening at 3 AM. And now I'm too energized to sleep, because I'm proud of my brain for working.
