“Utility is when you’re useful to each other. Say, a neighbor or a coworker or a client. While friendships of pleasure are when you enjoy each other’s company. Like you and your hiking buddies, for example. You enjoy doing certain activities together,” I explained. “Whereas friendships of good are based on mutual respect and admiration. Shared virtues and goals. You may not have many actual interests in common, but these people are your closest friends just the same. Isn’t that interesting?”
