Sound of Silence (Spooky Story)

It took me a couple seconds to wonder how he can speak when he’s been deaf his whole life

Speech therapy maybe? Some deaf people undertake it and can speak, even though they usually sound slurred

Sorry to reply to something this late
Deaf can talk, however it sounds nasaly, because that way of talking lets them feel the vibration and change of their voice.

My old friend

I've come to speak with you again.
