Do Not Talk Bad About Others, You May Need Their Help One of These Days

This happened many years ago when I am still in college. While I was doing my Diploma in Telecomunication and Computer Enginnering in KDU in the 80s, I was asked by Engineering Department Co-ordinator to teach software PCB design software to my juniors.

However, one day I was writing on board, I heard a voice saying "他有什么资格教我们." (What qualification do he has to teach us.) I recignized that voice of the student. He thought I do not understand Mandarin because I normally don't speak Mandarin last time. So after we graduated, we went our separate ways.

However, one day we crossed path again. The company I worked, happened to supply harddisk to his company. And, he required me to help him to exchange a damaged harddisk.

The moral of the story is DO NOT TALK BAD ABOUT OTHERS, YOU MAY NEED THEIR HELP ONE OF THESE DAYS.
