That such a thing bechanc'd would make me sad?
But tell not me; I know Antonio
Is sad to think upon his merchandise.

ANTONIO.
Believe me, no; I thank my fortune for it,
My ventures are not in one bottom trusted,
Nor to one place; nor is my whole estate
Upon the fortune of this present year;
Therefore my merchandise makes me not sad.

SALARINO.
Why, then you are in love.

ANTONIO.
Fie, fie!

SALARINO.
Not in love neither? Then let us say you are sad
Because you are not merry; and 'twere as easy
For you to laugh and leap and say you are merry,
Because you are not sad. Now, by two-headed Janus,
Nature hath fram'd strange fellows in her time:
Some that will evermore peep through their eyes,
And laugh like parrots at a bag-piper;
And other of such vinegar aspect
That they'll not show their teeth in way of smile
Though Nestor swear the jest be laughable.
