Who is Miss Stephanie Crawford and what is she like?

Miss Stephanie Crawford is an older woman, 60-ish, who has never been married and loves to gossip.  She is first introduced in the first chapter and we learn most of what we know about her in the early chapters.  It is from Miss Crawford that the children have learned most of the outrageous stories they've heard about Boo Radley.  Much of what Miss Crawford has told the children is not true or is an extreme exaggeration.  In chapter 5, when the children ask Miss Maudie if she thinks the stories about Boo Radley are true, she responds with, "That is three-fourths colored folks and one-fourth Stephanie Crawford." Miss Crawford is a woman with a little extra weight on her also.  In chapter 8 when Scout and Jem build a snowman with the rare snowfall, Scout comments that its fatness makes it resemble Miss Stephanie somewhat.  Essentially, Stephanie Crawford is the type of person most people know not to listen to.  They know that she is a gossip and that her information is either completely untrue or it is very exaggerated. She likes to over-dramatize situations and she likes the "Wow" factor she gets from people if she tells them something.
