Famous quotes containing the word twist:
“At first thou gav’st me milk and sweetnesses;
I had my wish and way:
My dayes were straw’d with flow’rs and happinesse;
There was no month but May.
But with my yeares sorrow did twist and grow,
And made a partie unawares for wo.”
—George Herbert (1593–1633)
