Famous quotes containing the words special, duty and/or locomotives:

    “‘I mean to retire, where
    Nobody will have heard about my special skills
    And conversation is mainly about the wearther.”
    —Eiléan Ní Chuilleanáin (b.1942)

    “[17th-century] Puritans were the first modern parents. Like many of us, they looked on their treatment of children as a test of their own self-control. Their goal was not to simply to ensure the child’s duty to the family, but to help him or her make personal, individual commitments. They were the first authors to state that children must obey God rather than parents, in case of a clear conflict.”
    —C. John Sommerville (20th century)

    “The flower-fed buffaloes of the spring
    In the days of long ago,
    Ranged where the locomotives sing
    And the prairie flowers lie low:—”
    —Vachel Lindsay (1879–1931)
