It's haunting

I have landed in Greenville, SC, and my suitcases and I are ready for the jewelry show tomorrow night! My brain is terribly consumed with jewelry, repairs, and loose stones. So much so that I woke up around the 2 AM hour with a gasp! "I think I put a 14k gold chain on a gold filled pendant! It's true. I did. But I just wonder why my brain told me at that hour. Jewelry haunts me.
