" The reality of social networking sites is that they provide platforms for online personae to interact with other online personae. Importantly, such relationships can be ended with a click of an 'unfriend,' 'unfollow,' or 'block' button. Breaking up like this constitutes a morally lightweight action. Certainly it flies in the face of Cicero's advice that a friendship 'should seem to fade away rather than to be stamped out.' The respect that Cicero demanded that we pay to a friendship, even one that has turned sour, did not anticipate the tenuous connection inherent in being a facebook friend. "
