Words.

The words entered left ear and flew out from right ear. They don't even encode in the brain to analyze, just went off without any vestige.

That's what most of us did when someone around you is trying to tell you something you don't feel good.
Listen is manner that we should learn. It's a sign of respect. Listen to your parents, listen to your love one, listen to the melody around you. Listen with your heart. Just stop anything on hand for a few minutes everyday. Pay attention to every single sound around you.

You'll find peace and tranquility.

Just try it ! TEEHEE ;)
