Riddle

Someday, my brother and i discussed about riddle, he asked me to answer a question. Thats a though one.
After that i have an idea to wrote a thing about riddle in blog. And there it is:

Riddle is a thing that people usually hard to understand
"What is the truth?"
That's the question which usually people anxious about.
Or maybe, "am i right?"

........

Some people really have some riddle in life. One doesn't know how to solve that kind of riddle and the other one doesn't need to be disturbed by this kind of thing.

The bad thing is when we can solve the riddle and the other one can't is we could be hated by the person who can't solved that kind of riddle.

So, the question is: "what is the point?"
Nah, what's the point of making riddle? Is it just to get the self confession for us to ranked better than the other? Or just to make other people jealous of what we have? Or there is another reason?
