When to choose the worthy doors of opportunity

MY wife keeps the refrigerator open while she's tinkering with some ice cubes for her drink. Likewise, she has the habit of half-closing a drawer of our steel cabinet where we keep important documents. I thought to myself: "What's so difficult about closing a refrigerator door or a cabinet drawer?" Isn't that an open refrigerator door wastes energy? And a half-open drawer may accidentally cause bruises to our arms?

Talk of the invisible perils of open doors, literally.
