PORTIA. I prithee, boy, run to the Senate House;
Stay not to answer me, but get thee gone.—
Why dost thou stay?
LUCIUS. To know my errand, madam.
PORTIA. I would have had thee there and here again
Ere I can tell thee what thou shouldst do there.
[Aside] O constancy, be strong upon my side;
Set a huge mountain ‘tween my heart and tongue.
I have a man’s mind, but a woman’s might.
–The Tragedy of Julius Caesar,
William Shakespeare
