Early on, Polonius and Laertes are over-protective of Ophelia and rather too cynical of Hamlet wooing intentions. Polonius soon changes his mind about Hamlet, attributing his dark depression to sincere, though unrequited, love. In the words of Polonius:
I am sorry that with better heed and judgment
I had not quoted him. I fear'd he did but trifle
And meant to wrack thee; but beshrew my jealousy!
By heaven, it is as proper to our age
To cast beyond ourselves in our opinions
As it is common for the younger sort
To lack discretion.
And
I will leave him and suddenly contrive the means of meeting between him and my daughter.
And
Ophelia, walk you here.- Gracious, so please you,
We will bestow ourselves.- [To Ophelia] Read on this book,
That show of such an exercise may colour
Your loneliness.- We are oft to blame in this,
'Tis too much prov'd, that with devotion's visage
And pious action we do sugar o'er
The Devil himself.
