Intonation

This has been bothering me for a great while, and now is just endemic:
Everyone? Here? Raises every statement that they are telling you? As like, a question?

And then there’s the ‘thank you.’ It sounds like “Hank-KYOUU!!” from every female I’ve come across locally. This was pointed out to me by a screenwriter whose name escapes me, I feel I need to give him credit; hankkyOOOO!!!.
He tells me this intonation has taken the country by storm, I believe him.
So like, I was like, you know? Um. HANKKYOOO!!!!
