"Oh, that a man might know The end of this day's business ere it come! But it sufficeth that the day will end, And then the end is known" and "But this same day. Must end that work the ides of March begun; And whether we shall meet again I know not. Therefore our everlasting farewell take: For ever, and for ever, farewell, Cassius! If we do meet again, why, we shall smile; If not, why, then, this parting was well made".
