I own nothing of Hey Arnold except the characters and elements I thought up myself.
He never said much as a child.
He said even less as an adult.
He said nothing at all after he came to America.
People assumed he was mute for that reason, both here and back home.
Oh well, he never considered himself a man of many words anyway. That didn't mean his silence never frustrated him sometimes.
That would probably explain so many folks got the impression of him being a push-over.
So imagine the surprise on the boarders' faces when he came home one day with a guitar in his hand.
His response: "I wanted to buy one."
And thus Mr. Hyunh's love for country music began!
