If you are in happiness, others feel jealous of you. Some of them may even look at you as though something is wrong with you. If you look sad, others will say: 'Look at that guy. He looks so morose. Seldom I see a smile on his/her face.' And if you are neutral, not given much to display of feelings or emotions, they will say: 'Look, that person is so dull. He has no human feelings. He is like a log. He is a log.' This is what we humans are, accept it or not.
