Theories of Argumentation class would be a lot more interesting if we could learn to master the techniques of argumentative discussion that we used as wise young children.
And out of the mouths of babes:
"Nu uh!"
"Yuh huh."
"Nu uh."
"YU huh!"
"Nu UH!"
"Yea Huh, yea Huh, yea HUH."
"Nu UH nu UH nu UUUUUH."
"Yep."
"Nope."
"Yea huh."
"Nu uh."
Things made more sense then.
