Exit, pursued by a bear. - William Shakespeare

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-hatched unfledged comrade. Beware Of entrance to a quarrel, but being in, Bear’t that th’opposèd may beware of thee. Give every man thy ear, but few thy voice; Take each man’s censure, but reserve thy judgement. Costly thy habit as thy purse can buy, But not expressed 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, 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 own self be true; And it must follow, as the night the day, Thou canst not then be false to any man.

We came into the world like brother and brother,
And now let's go hand in hand, not one before another.

"But, indeed, words are very rascals, since bonds [vows] disgraced them."
Viola: "Thy reason, man?"
Feste: "Troth [Truthfully], sir, I can yield you none without words, and words are grown so false, I am loathe to prove reason with them."
