Read the excerpt from Act II of Hamlet.

Ophelia: Alas! my lord, I have been so affrighted.

Polonius: With what, in the name of God?

Ophelia: My lord, as I was sewing in my closet,
Lord Hamlet, with his doublet all unbrac'd;
No hat upon his head; his stockings foul'd,
Ungarter'd, and down-gyved to his ancle;
Pale as his shirt; his knees knocking each other;
And with a look so piteous in purport
As if he had been loosed out of hell
To speak of horrors, he comes before me.
