Let me go: take back thy gift: Why should a man desire in any way To vary from the kindly race of men, Or pass beyond the goal of ordinance Where all should pause, as is most meet for all?...Why wilt thou ever scare me with thy tears, And make me tremble lest a saying learnt, In days far-off, on that dark earth, be true? 'The Gods themselves cannot recall their gifts.' - Tithonus
