The news caused Maria to suddenly burst out in song, belting out a surprisingly accurate rendition of a cheesy pop song. She grabbed a nearby hairbrush and used it as a microphone, twirling around in a circle.

Then, she paused, and started to laugh hysterically, shaking her head. "You're going to the other side of the country? Without me?" She could hardly believe it.

She then went to the kitchen and grabbed a box of cereal, dumping the entire contents onto the floor. "Time for a cereal fight!"
