When you meet someone, you are most commonly asked "What kind of music do you like?" or “What is your favorite genre of music?” or some other easy question that establishes common interests. Aristotle would most likely call these friendships pleasant friendships, unless they later evolved into perfect friendships based on virtues. That's because having these common interests is nice—it gives friends something to talk about and bond over—but common interests alone rarely allow friends to encourage each other to be better people. Interests create strong friendships, but unless virtues come into play, interests do not create lasting friendships
