原文&自翻译
When you are old and grey and full of sleep,
And nodding by the fire, take down this book,
And slowly read, and dream of the soft look
Your eyes had once, and of their shadows deep;
当你老了，头发灰白，在炉火旁打着瞌睡，睡意朦胧，拿下这本书，慢慢的阅读。梦到你眼中曾有的一次温柔，和眼中深处的影幻。
How many loved your moments of glad grace,
And loved your beauty with love false or true,
But one man loved the pilgrim soul in you,
And loved the sorrows of your changing face;
多少人爱你光鲜耀眼的时刻，爱你美丽、虚伪或真实。唯有这个男人（我）爱你朝圣者般的灵魂，爱你变换的面孔上的忧伤。
And bending down beside the glowing bars,
Murmur, a little sadly, how Love fled
And paced upon the mountains overhead
And hid his face amid a crowd of stars.
［这段不知道情景，太难翻了］
在闪亮的栅栏旁低下腰，伤心的低语着逝去的爱情。踱步在山顶，把他（伤心）的面孔融入到群星中。
［bar别人都翻译成酒吧，我觉得栅栏更好，因为后面有mountains和stars都是室外的场景］
