to know everything doesn't equal happiness

Say, you are all ears and that makes you know everything. Some request for problem solving, some just to express their feelings. You extract everything, trying to comprehend each narration since sometimes it has connection to each other.

After that, you get nothing but headache!

So, my conclusion up to now, is that to know everything doesn't equal happiness. Why so extreem?

Say, if the story is a happy one, you can smile widely til your lips get confused to get back to its normal position. But do people tell their happiness more than they tell sadness? Ha! And sometimes, one's happiness could somebody else's sadness. After listening to the happy person then the sad one also comes to you and share the sorrow with the same subject but different point of view.

I don't see any pleasure of being in the middle like that. Got it now?
