+
+ 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.
