Most friendship is feigning, most loving mere folly.

To become reconciled to a friend with whom you have broken, is a form of weakness; and you pay the penalty of it when he takes the first opportunity of doing precisely the very thing which brought about the breach.

Et tu, Brute!

...Who could refrain,
That had a heart to love, and in that heart
Courage to make love known?

Friendship is constant in all other things
Save in the office and affairs of love.
Therefore all hearts in love use their own tongues.
Let every eye negotiate for itself,
And trust no agent; for beauty is a witch
Against whose charms faith melteth into blood.

DON PEDRO
Come, lady, come; you have lost the heart of Signior Benedick.

BEATRICE
Indeed, my lord, he lent it me awhile; and I gave him use for it, a double heart for his single one: marry, once before he won it of me with false dice, therefore your grace may well say I have lost it.

DON PEDRO
You have put him down, lady, you have put him down.

BEATRICE
So I would not he should do me, my lord, lest I should prove the mother of fools.
