A Point in Time

"Are you happy?" What a simple question but one that left me stumped! I have no answer to it and I guess no one really does. Happiness is such a relative feeling because each person will measure their happiness in different terms. What makes you happy could be something useless for another person. I always prided myself in being a happy person and have stated time and time again that my happiness comes from within me and is not dependent on anyone or anything. But this question, made me question myself and my standard of happiness. I wondered if in trying to be happy, had I lost the meaning of what happiness meant to me?
