| 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 |

| Farewell, Ophelia; and remember well |
