Earlier this week, one of my troubled friend suddenly asked me out of the blue "How come you're happy everytime?" I never have really thought that way until today I realized that I was voluntarily indulging in sadness whenever I'm alone; It would explain how he always perceive me to be always happy. I honestly never had felt sad for others yet I find myself tearing up with sad fictional stories. Is it abnormal to only find sadness in an artificial way? Am I emotionally healthy?
