I had to Google Day. I'm still none-the-wiser
Anecdote: When I was in primary (elementary) school, I took some classes separately and was tutored alongside the deaf children at my school. Initially they thought I may have difficulty hearing, so I was tested. It turned out that my hearing was in fact above average, My brother would throw tantrums at home and I had learned to block out annoyances. I deemed the teacher to be an annoyance and just blocked her out lol.
I have a great ear for detail, very quiet sounds, and pitch (used to tune violin from memory, afterwards not hear any beats when played alongside a tuner, but now I mostly forget which letter corresponds to which pitch since I haven't played in a decade), but sometimes when people talk it takes a second for the meaning to "click" with me, and at 27 years old I can't hear "the most annoying sound in the world" audio sample when my cousins were playing it on their phones. Joke's on them, haha.
Whenever I hear his name I can only think of the Halloween when he played Amnesia: The Dark Descent and ended up being a screaming little girl for several hours. Such a fun few nights of streaming. That game freaked me out when I played through it so it's fun watching others succumb to it's incredible atmosphere and story telling.
