Emmy is a pro at discovering people buttons, and then just pushing it endlessly.
At day care, Emmy met a little boy (Brady) who she thinks is fond of Meron. So Emmy starts in with "Meron naughty". Sure enough, Brady stands right up for Meron. "No she is not. Meron is a nice girl. I like her".
Big mistake. Emmy practically puts herself into a trance with her incessant monotone chant of "Meron naughty". Brady was having a triple heart attack in his zeal to defend Meron's honor. While Brady is flailing and sputtering, Emmy just sits as calm as the eye of a hurricane, expressionlessly staring at Brady, secure in the knowledge the teachers will not let Brady hit her, and taunts Brady with "Meron naughty".
