Shrinking Sister

Sarah winced as she heard her little brother's words, fearing she was about to grow even younger than his ten years. Instead, something else happened. Ryan stood in fear as Sarah moved in on him, ready for her no-doubt violent retribution. But, as she approached, Ryan looked bigger and bigger. His eyes were doing the same, widening with each step. Sarah had already wished herself older -- the stone wouldn't make her any younger -- but it would certainly make her smaller. In moments, Sarah was frozen in her footsteps, about four feet tall, and just looking up at her much larger now-younger brother.
