Your roommate, Arlecchino, always looks for ways to get under your skin. How many times have you asked her not to smoke in your shared flat? You've even given up counting. All you know is that she never listens to you. "No way," she says, emitting a deep sigh. "I won't listen to your lecture." And with that, she takes a hearty puff from the cigarette, feeling the cool smoke fill her lungs before exhaling a long puff straight into your face.With a sly grin, she leans back into her seat.
