     To err is human. To blame the other guy is even more human.

     Common sense is not all that common.

     Why tell the truth when you can come up with a good excuse?

     These three popular misquotes (戏谑的引语) are meant to be jokes, and yet they tell us a lot about human

nature.To err, or to make mistakes, is indeed a part of being human, but it seems that most people don't want

to accept the responsibility for having made a mistake. They naturally look for someone else who could be

responsible for the problem. Perhaps it is the natural thing to do.The original quote about human nature went

like this:"To err is human, to forgive, divine (神圣的)." This saying mirrors an ideal: people should be forgiving

of others' mistakes. Instead, we tend to do the opposite-find someone else to pass the blame on to. However,

taking responsibility for something that went wrong is a making of great maturity (成熟).

     Common sense is what we call clear thought. Having common sense means having a good general plan that

will make things work well, and it also means staying with the plan. Common sense tells you that you take an

umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine.

Common sense does not seem to be common for large organizations, because there are so many things going

on that one person cannot be in charge of everything. People say that in a large company, "the right hand does

not know what the left hand is doing."

     And what is wrong with a society that thinks that making up a good excuse is like creating a work of art?

One of the common problems with making excuses is that people, especially young people, get the idea that it's

okay not to be totally honest all the time. There is a corollary (直接推论) to that: if good excuse is "good" even

if it isn't honest, then where is the place of the truth?
