Act 2, Scene 1, Paragraph 562

Thus answer I in the name of Benedick,
But hear these ill news with the ears of Claudio.
‘Tis certain so; the prince wooes for himself.
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.
This is an accident of hourly proof,
Which I mistrusted not. Farewell, therefore, Hero!
