That reminds me of how every other time I silence/unsilence my iPhone, I stare at the "Silence activated" / "Silence deactivated" and work out in my head if it means the phone will make noise or not. Despite doing it thousands of times.

I suppose "Sound on" vs "Sound off" would be better because in the moment I'm thinking of noise and sound, so silence is the inverse of that and kinda forms a double negative situation. "Not-noise mode activated / not activated".
