Fluency in one usually means fluency in both, unfortunately for everyone.

You picked up sarcasm early and never looked back, using it as your primary form of communication since roughly middle school. The cursing came a little later, but it caught up fast. Now the two run together so smoothly nobody can tell where one ends and the other begins.

People assume you'll tone it down for polite company, professional settings, family dinners. That assumption has never once been correct. Both languages come out regardless of the audience.

Rebel Ink speaks both fluently too.
