That's when everything I've been holding in since this morning, since when Mrs. Price put the sweater on my desk, finally lets go, and all of a sudden I'm crying in front of everybody. . . . I put my head down on the desk and bury my face in my stupid clown-sweater arms. My face all hot and spit coming out of my mouth because I can't stop the little animal noises from coming out of me, until there aren't any more tears left in my eyes, and it's just my body shaking like when you have the hiccups, and my whole head hurts like when you drink milk too fast.
