even in laughter a heart is sorrowful

As I was thumbing through my Bible and looking for importaint spots that I had underlined for myself about 2years ago I found an interesting passage that really made me think. Proverbs 14:13 says, Even in laughter the heart is sorrowful; and the end of that mirth is heaviness. I haven't really thought about this concept before but today as I was driving home from church I realized how true this truth was.
You know how sometimes you say that you feel well when somebody asks you how are you even though alot of times you know that it is not how you trully feel, or you laugh along with everybody else although inside you might be hurting. And so I decided to take a step back and go throught my life to see how much times I have played this pretend game. I realized with horror that about 5/10 times that I smiled, laughed or said I felt good were executed with sorrow in my heart, and most of those times I felt that it was the right thing to do and did not want to center the conversation around my troubles.
I also felt as if I had cheated myself and the people that I laughed with because my mirth was not genuine, and many times was forced. I think that most people, including myself do not have the time or the energy to dwell on the fact that alot of the actions we perform are those that are expected of us by our peers, bosses and almost everybody else. Nobody wants to come in and see a sour face or a frown, so most of us have to constantly fake a smile a laugh and hide our pain in order to function efficiently in society.
