To think that two and two are four And neither five nor three The heart of man has long been sore And long 'tis like to be.

To think that two and two are four And neither five nor three The heart of man has long been sore And long 'tis like to be.

一想到二加二等于四，既不是五也不是三，人的心就会长久地感到痛苦，而人的心也会长久地感到痛苦。

-- Alfred Edward Housman 豪斯曼
