" Something hit the floor with a crack. Nate turned and looked down to see his cell phone on the floor. He patted his back pockets, as if to be sure it was his, then swore and reached down. The phone slid across the floor.
“What the hell?” he muttered.
It slid faster now, scraping and bumping along.
“Carter!” Nate growled. “This is not the time for pranks.”
As he took off after the phone, I looked out the bathroom door to see it rise a foot off the ground, then fall with a crack.
Nate swore and picked up speed, loping down the hall, muttering. “If you break it, Carter, I swear you’re buying me a new one.” "
