O'Malley: Mo kah-kah!
Me: You need some more crackers, O'Malley?
O: (shaking his head no firmly with a big smile) NO!
Me: Okay. You mean yes.
(I pour him more. He starts to eat.)
Snow White: He say no. Why you give him more?
Me: Well, he doesn't understand sometimes which word to use. He means yes.
Snow: But he say no. He shake his head like THIS. NO!
Me: I know. He's confused.
Snow: He not need crackers! He say NO!
Meanwhile, O'Malley's chomping away happily on the second helping, which he definitely did want. Poor Snow. Confusion is no fun.
