What if magic was real, but it was treated like music with different genres and you're like "Oh, you're into conjuring? That's cool, I guess. Recently I've been getting into third-wave post necromancy. It's some pretty heavy stuff."
"What? You've never learned Fireball? Its a classic!"
"I don't know; I'm not really into evocations."
"How an you not be into ANY evocations?"
"Its kinda like dad magic, y'know?"
