RALPH: Polonius is quick to assume that he understands Hamlet's behavior. He doesn't seem to notice that his interpretation is completely at odds with his previous understanding of Hamlet. You'll remember in Act I, scene 3, he was convinced that Hamlet was just toying with Ophelia and wasn't truly interested in her.

SARAH: Polonius is also quick to see blame elsewhere: he immediately asks if Ophelia has said anything to hurt Hamlet.

RALPH: But all Ophelia has done is to follow her father's orders, and to refuse to see Hamlet. These lines also give us a clue that some time has passed since Act I, and that Hamlet has indeed tried to get in touch with Ophelia, however unsuccessfully.
