+       O, fear me not.
+       I stay too long: but here my father comes.
+
+       Enter POLONIUS
+
+       A double blessing is a double grace,
+       Occasion smiles upon a second leave.
+
+LORD 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 thee!
+       And these few precepts in thy memory
+       See thou character. Give thy thoughts no tongue,
+       Nor any unproportioned thought his act.
+       Be thou familiar, but by no means vulgar.
+       Those 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, unfledged comrade. Beware
+       Of entrance to a quarrel, but being in,
+       Bear't that the opposed may beware of thee.
+       Give every man thy ear, but few thy voice;
+       Take each man's censure, but reserve thy judgment.
+       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 of a most select and generous chief 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 ownself 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!
+
+LAERTES 
+
+       Most humbly do I take my leave, my lord.
+
+LORD POLONIUS 
+
+       The time invites you; go; your servants tend.
+
+LAERTES 
+
+       Farewell, Ophelia; and remember well
+       What I have said to you.
+
+OPHELIA 
+
+       'Tis in my memory lock'd,
+       And you yourself shall keep the key of it.
+
+LAERTES 
+
+       Farewell.
