My college tutor told me that "Communication" is the most difficult topic in the world.  I didn't realize the meaning behind this statement but now, I do.

When you tell a joke, the people around you don't laugh - not because the joke is not funny but they mis-interpret the story.  You share with them your sad feeling but they tell you theirs in return - not because they don't care but they think theirs are worst than yours (you know, people like to "compare").

Next time, I would find a better audience before the communication process begins.
