    “O tiger’s heart wrapped in a woman’s hide!
    How couldst thou drain the lifeblood of the child,
    To bid the father wipe his eyes withal,
    And yet be seen to bear a woman’s face?
    Women are soft, mild, pitiful, and flexible;
    Thou stern, obdurate, flinty, rough, remorseless.”
    —William Shakespeare (1564–1616)

    I fatherly will kiss and daut thee,
    As dear an’ near my heart I set thee
    Wi’ as guid will,
    As a’ the priests had seen me get thee
    That’s out o’ hell.”
    —Robert Burns (1759–1796)
