The plot of a story is like a roadmap that takes the reader from point A to point B. In every story there is movement or change; without such changes, there's no story. Every story, of course, is different, and there are many kinds of changes that affect how a story proceeds. A character can experience change both physically and mentally. These changes can be brought about by the actions or influence of other characters, and the changes may be deliberate or unintended, sudden or prolonged. These changes, in turn, can cause a shift in the reader's perception. For example, a character may seem to be insensitive and mean, but the reader later realizes that he is actually gentle and kind.
