] "These words, like daggers, enter in mine ears;"

A hearing image we didn't talk about last week, eh? Hamlet says he will speak daggers to her, so he should feel so proud...

] some remorse, some acknowledgement that she did not behave as she ought.

I believe that Gertrude was weak and married Claudius out of desperation. With her husband dead, where is she going to get the male attention that she lives for? Enter Claudius, all about male attention, flattery, and forgetting that you were ever sad about anything.

Now that some time has past, Gertrude's panic has subsided, and she is more free to think about the fact that she was hasty, and she knows that Hamlet thinks she was. He's been telling her that for months.

Add to that fact the fact that she married her husband's brother, which was considered incestuous in some cultures and must have some of that cast in Denmark, or Hamlet and the Ghost wouldn't continue to call it that.

So when he says these things to her yet again in this very emotional scene, she is ready to hear it and acknowledge it--she knows that it was wrong, and that she has made huge decisions when she was at her most needy and least sensible.

That's the guilt that she is ready to admit, and she has all but admitted it, and then Hamlet starts speaking to the air.

What's that about???

Why can't Gertrude see the ghost???
