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)
