Encourage your S do do this, don't throw your typical wet blanket on it.
I have encouraged it because I know it will blow up in my face if I don't. I've mentioned a few dozen times here that my kids are (nicely) calling me out on my negativity. I hate being wrong, crow doesn't taste very good and I'm tired of burning my hand on a hot stove. Part of my evolution is being aware of peoples reactions and facial expressions. When I'm negative people go quiet, frown, and quickly try to escape. I may not be positive (yet) but I have gotten good about keeping my mouth shut.
