            'Left Ear In, Right Ear Out' conveys an attitude towards things not being taken seriously, where information or suggestions are quickly forgotten or not retained. It describes a state of distraction or lack of seriousness, where thoughts or words do not linger, reflecting carelessness or intentional disregard.
