You look not well, Signior Antonio

Gratiano
You look not well, Signior Antonio.
You have too much respect upon the world.
They lose it that do buy it with much care.
Believe me, you are marvelously changed.
Antonio
I hold the world but as the world, Gratiano,
A stage where every man must play a part,
And mine a sad one.Simile
Gratiano
Let me play the fool.
With mirth and laughter let old wrinkles come,
And let my liver rather heat with wine
Than my heart cool with mortifying groans.Alliosis
Why should a man whose blood is warm within
Sit like his grandsire cut in alabaster?Simile
Sleep when he wakes? And creep into the jaundice
By being peevish? I tell thee what, Antonio
(I love thee, and 'tis my love that speaks):
There are a sort of men whose visages
Do cream and mantle like a standing pondSimile
And do a willful stillness entertain
With purpose to be dressed in an opinion
Of wisdom, gravity, profound conceit,
As who should say “I am Sir Oracle,
And when I ope my lips, let no dog bark.”
O my Antonio, I do know of these
That therefore only are reputed wiseHyperbaton
For saying nothing's, when, I am very sure,
If they should speak, would almost damn those ears
Which, hearing them, would call their brothers fools.
I'll tell thee more of this another time.
But fish not with this melancholy bait
For this fool gudgeon, this opinion.Metaphor
