Polonius

As Laertes is saying goodbye to his sister, Polonius enters the stage and interrupts their private chat in act i, scene 2, lines 59 to 85:

• Polonius:   Yet here, Laertes? Aboard, aboard, for shame!
• The wind sits in the shoulder of your sail,
• And you are stay'd for. There; my blessing with you!
• And these few precepts in thy memory
• See thou character. Give thy thoughts no tongue,
• Nor any unproportion'd thought his act.
• Be thou familiar, but by no means vulgar.
• The friends thou hast, and their adoption tried,
• Grapple them to thy soul with hoops of steel;
• But do not dull thy palm with entertainment
• Of each new-hatch'd, unfledg'd comrade. Beware
• Of entrance to a quarrel; but being in,
• Bear't that the opposed may beware of thee.
• Give every man thine ear, but few thy voice;
• Take each man's censure, but reserve thy judgement.
• Costly thy habit as thy purse can buy,
• But not express'd in fancy; rich, not gaudy;
• For the apparel oft proclaims the man,
• And they in France of the best rank and station
• Are most select and generous in that.
• Neither a borrower nor a lender be;
• For loan oft loses both itself and friend,
• And borrowing dulls the edge of husbandry.
• This above all: to thine own self be true,
• And it must follow, as the night the day,
• Thou canst not then be false to any man.
• Farewell; my blessing season this in thee!
