I was reading the kiddo a bed time story when she stumped me with a question. In the story a woman "nodded". And then the kid says "if nodding means yes, then what means no?" And I said "well that's when you shake your head, that means no or to disagree". And she says "yeah, I know that. But why isn't there just one word that means that, like nod"? Huh. Kids are clever with noticing oddities that we have forgot or just never paid attention to.
