The news caused a giggle to escape from Mia's lips. She felt a lightness, as if she could float right out the window. She skipped, and she couldn't stop.

She felt the need to be physical. She decided to climb the fire escape, just for the thrill. She made up a song about the building’s demise. She yelled, just to get the sound out.

She had to make a splash. She decided to go to the local store and buy a water gun. She spent an hour hiding behind bushes, squirting anyone and everyone.

She felt like a kid again. She planned to leave a trail of laughter in her wake. She wanted to fill the building with joy, before the change.
