That made you break this enterprise to me?

When you durst do it, then you were a man;

And to be more than what you were, you would

Be so much more the man. Nor time nor place

Did then adhere, and yet you would make both.

They have made themselves, and that their fitness

now

Does unmake you. I have given suck, and know

How tender ’tis to love the babe that milks me.

I would, while it was smiling in my face,

Have plucked my nipple from his boneless gums

And dashed the brains out, had I so sworn as you

Have done to this.
