I have seen many people and I have few friends also who doesn't have any interest in celebrating the birthdays or enjoying parties and making new friends. They are just into themselves and just stay away from people and separate from the life I would say. And just running towards the running towards the painful truth which is death at last if we all doesn't enjoy life to the fullest because life is something which is very precious and God gifted so we have to leave it at which we have to live it
