Sometimes you realize you’re worried but you can’t remember what you’re worried about. You know there’s something out there, a thing that was worry-worthy. You ransack your memory. Gone. It has become a stray worry. It’s a worry on the loose, no doubt rambling all over the neighborhood, causing trouble. It may be hours, days or even months before it returns. This REALLY worries you. Because if you want to keep your sanity you need to keep your worries front and center, where you can watch their every diabolical move.
