把这一句，留给此刻的你

Bad company is like a nail driven into a post, which, after the first and second blow, may be drawn out with little difficulty; but being once driven up to the head, the pincers cannot take hold to draw it out, but which can only be done by the destruction of the wood

坏伙伴就像钉在柱子上的钉子，第一次和第二次打击后，可以毫不费力地拔出来;但是，一旦被赶到头部，钳子就抓不住它，无法把它拔出来，而这只能通过破坏木头来实现

— Saint Aurelius Augustine 圣奥勒留奥古斯丁
