Teachers are human too -- failure is around us all the time. So cheer up my students who worry about the final grade

An old friend (and former grad student) of mine who kindly inspired me and took me to this blogger recently indicated that her hands were tied by school work, family obligations and so on. She has to stop sharing her wonderful thoughts here indefinitely. How sad!
Yes, we all are exhausted. Are we accomplishing meaningless task by investing countless hours? Nobody knows and I doubt that anyone would really care.
On one of these sleepless nights I could not do any work. I chose to write something that is completely out of my students' expectation. They are in Chinese however.

我把我的淚串成珍珠
隨時地掛在我心上
幻想成為她最美的首飾
因為每一顆珍珠 　　
都是我最珍貴的淚

我把它藏著心底 　　
隨時提醒我
同樣的錯　　同樣的傷 　　永遠不會有第二次

每一天 　想一遍
在夢裡
她回首一笑
珍珠鍊子斷了
我的淚灑落一地
踩著一地水
她溫柔地問
答應她的珍珠項鍊在那兒？

我哭泣一夜
為了一串新的珍珠項鍊
淚水終於乾了
她卻不再問我
答應她的珍珠項鍊在那兒？
