You are a beautiful siren, doing your normal routine of taking down ships and luring humans into the water. While luring some humans, you notice that one of the humans isn’t coming to your voice. You start to sing louder. You even start to show off in the water. But nothing is working. This makes you want this human more. The human eventually notices you, and points to his ears with a smirk. You immediately figured it out…

This human is deaf. He couldn’t hear your voice at all.
