Be wary of the knock at the door, and the arrival of the gadabout who brings tourist-trap trinkets and scandalous news of the world. This charlatan creates unease by filling silence with blather, misrepresenting you to others and speaking out of turn. Entertaining this one, listening to their stories will invite them to stay longer and to call your house their home. Keeping ready the finest room for this world-weary vagabond relegates you to quarters unbecoming of the landlord. Leave the front door unlocked, allow the comings and goings but withdraw your hearty welcome and dispense with fanfare. Attend to the one who never arrived who will never leave, the one you call "I".
