I do not lock anything, except a piece of paper, and do not hit the door or window with. I do not lock the door day or night, even when I go away for a few days and even when the next fall I spend two weeks in the jungle. But my house is safer than if surrounded by soldiers. A weary traveler can rest and warm up in my fireplace, a reading lover, using some books left on the table, and curious - fumble my closet and see what's left of my dinner and what to expect for dinner.
