From Julius Caesar, Act II, Scene I: Portia

Is Brutus sick? and is it physical
To walk unbraced and suck up the humours
Of the dank morning? What, is Brutus sick,
And will he steal out of his wholesome bed,
To dare the vile contagion of the night
And tempt the rheumy and unpurged air
To add unto his sickness? No, my Brutus;
You have some sick offence within your mind,
Which, by the right and virtue of my place,
I ought to know of: and, upon my knees,
I charm you, by my once-commended beauty,
By all your vows of love and that great vow
Which did incorporate and make us one,
That you unfold to me, yourself, your half,
Why you are heavy, and what men to-night
Have had to resort to you: for here have been
Some six or seven, who did hide their faces
Even from darkness.
