Often, we tend to ignore when people are talking to us. However, we tend to listen when the things said are not meant for us to listen -- which we often hear people say " kaypo". After hearing those things that were'nt meant for us to hear, assumptions, guesses and illusions will start to cloud our mind. Eventually, nothing but trouble comes. At the end of the day, we feel upset about everything....but initially, things was not the way it was.
So, NEVER HEAR WHAT WAS NOT MEANT FOR YOU
