The Tragedy of Hamlet, Prince of Denmark — Act 1, Scene 3: A room in Polonius' house.

Laertes prepares to leave Denmark and gives Ophelia a long warning about Hamlet, telling her not to trust his affection or give him too much of her time. Ophelia replies that she will remember his advice, but she also criticizes the way he lectures her while not always acting by the same rules himself. Polonius arrives, sends Laertes off with a blessing, and then adds his own practical advice about self-control, friendships, quarrels, money, and honesty. After Laertes exits, Polonius asks Ophelia what Laertes said. She tells him it concerned Hamlet, and Polonius questions her closely about Hamlet’s attentions. When Ophelia admits Hamlet has made love vows to her, Polonius orders her to avoid him.
