Famous quotes containing the words sets and/or follow:

    Music sets up ladders,
    it makes us invisible,
    it sets us apart,
    it lets us escape;
    but from the visible
    there is no escape.
    Hilda Doolittle (1886–1961)

    “If you do!” She was opening the door wider.
    “Where do you mean to go? First tell me that.
    I’ll follow and bring you back by force. I will!”
    Robert Frost (1874–1963)
