Then something happened. I felt a tug in the pit of my stomach. I heard the plumbing rumble, the pipes shudder. Clarisse’s grip on my hair loosened. Water shot out of the toilet, making an arc straight over my head, and the next thing I knew, I was sprawled on the bathroom tiles with Clarisse screaming behind me. I turned just as water blasted out of the toilet again, hitting Clarisse straight in the face so hard it pushed her down onto her butt. The water stayed on her like the spray from a fire hose, pushing her backward into a shower stall.
