(it is consider yelling when the sentence is all written in capital letters).
He answers "Sure" if you ask him something without yelling, for example "Is everything ok with you?"
He answers "Quiet, I am thinking!" if you yell a question at him. "HOW ARE YOU?"
He says "Just say something!" if you address him without actually saying anything.
