A: Mary is complaining about her headache again. Is she really sick or is she just crying wolf?

B: Each time I ask her to help with extra work, she has a headache. I doubt if she’s really unwell.

Note: This idiom means to “cry or complain about something when nothing is really wrong.” 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. The expression has been applied to any false alarm since the mid-1800s.
