No means No, stop. cease, desist.,.
Let's have one "No" definition
It's just as easy to say "I see" than to say "I kNOw," it doesn't make you a "know-it-all," it's 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, constantly say "I don't know," "I do NOt kNOw," aka "I do no no."
