Olivia has created an alter-ego.
She ran around all morning snicker and saying, "I"m Evil Girl!"
She dropped guacamole on the floor. I told her that wasn't nice. She replied, "No Mom, it's not nice - it's EVIL!"
... we may need to stop watching Phineas & Ferb.
And I may need to reevaluate my parenting if she's relating more to the villains in these TV shows.
