My husband and I own a commercial construction company. For some time, I've kept one of the company's dark blue hard hats in my office. That way I have one to wear that isn't too gross when I need to visit a job. From time to time, a hard hat would disappear from my office. That's okay. They are the ones banging sheet metal. They need 'em. I'm just a looky-lou. I'd get another and be fine for a while, then the new one would go missing. Then another and another. I've been through a bunch of blue hard hats.
