the boy who cried wolf

Someone who claims that something is happening when it really isn't, which results in the rejection of subsequent valid claims. The expression comes from one of Aesop's fables, in which a young shepherd lies about a wolf threatening his flock so many times that people do not believe him when he and his flock are legitimately in danger. I'm sure there's no real crisis—Janet is like the boy who cried wolf, trying to get us to do her work for her.
