Justin started laughing. Seriously the whole thing had been hilarious, he had been walking one minute and then falling the next. Riot. He rolled over till he was on his back looking up her, still laughing mind you. "I guess I can't ignore the laws of physics. You know? What goes up, must go down?" Apparently that was funny too, because Justin was entering another round of laughter shortly after saying it.
"We could totally do it down here on the floor you know."
