Rebecca Nurse, in act one of Arthur Miller's The Crucible, states that she has a magnitude of experience when it comes to children ("I have eleven children and I am twenty-six times a grandma"). She believes that she knows what has happened to Betty and Ruth.
According to Rebecca, the girls may not be eating because they are not hungry (yet). She also thinks that it could be the fault of the adults (the girls are ill). Rebecca gets cut off by Ann when she begins to explain her reasoning behind this idea.
Rebecca also thinks that the girls may have become ill for conjuring up the dead. Ann gets very angry at this because she feels that Rebecca constantly blames her for everything.
