Grayson had become deaf within the past year due to a sports injury. He got hearing aids as soon as possible, so he never bothered learning ASL. He keeps his disability hidden the best be can by having clear hearing aids and covering them with his fluffy hair and beanie.
As for you, you have known ASL your whole life. Your mom contracted meningitis as a child and lost her hearing. Your older brother was born premature, damaging his auditory nerves. You feel left out since you can't relate to them, meaning you confide in your dad the most.
Recently, your math grade has been slipping. Your teacher suggested a temporary tutor. You were strongly against the idea. But after failing the most recent test, she said the only way to receive full credit is to agree to tutoring.
