@Anoyjoot & Brownmane
Sometimes I fall down the youtube rabbit hole and to my surprise, I found old episodes of chills narrating in a perfectly normal voice. It is hard to believe but, I think he does it out of sheer laziness. He does have a clip on his channel that supposedly answers the question why he chooses to speak that way but, I guess I"m just not interested enough to watch.
@Swifty, okay but what did you think of that little toddler saying goodbye to grandma at the graveyard and leaning forward with her head raised to give her a kiss at 20:05 ?
