I’ve spent a lot of time lately thinking about the Italian word umarell. Per wikipedia, it literally means “little man,” but is also widely used to refer to retirees who stop in the street to watch construction, stereotypically with hands clasped behind their back. In my household it’s become a verb: to watch someone at work, usually while standing somewhere inconvenient, especially while peppering the worker with questions and exclaiming “fascinating.” The clasped hands are optional, though in practice they feature more often than not.
I learned from the Pantheon you only need one window, if it’s big and in the center of the ceiling. I learned that again at Back Bar.
