Let there be no question what that sound means

It's just as easy to say "I see" as it is to say "I kNOw." And not saying "know" doesn't make you a "know-it-all." it's also much clearer, but most important of all, it raises Children to have no doubt about the meaning of the word "No." And I can stop hearing Donna, not my sister Donna, constantly say "I don't know," "I do NOt kNOw," aka "I do no no."
