I’ve met many a children who idolize the word “No”. Or, more accurately, “NOOOOOO!NO!NO!NO!NO!NO!”
Goober (so far) does not use “no” in this manner.
Instead, he only uses it if you ask him if he wants something or wants to do something that he doesn’t, and he’s so polite about it.
“Goober, do you want some juice?”
Very matter-of-fact, but in his sweet little voice, it’s the cutest use of “no” I’ve ever heard.
