I like to smile! I don't smile when I get up in the morning though, because I'm not a morning person. I don't know how people can be cheerful so early in the morning. Some people don't like to smile I guess. Did you ever see a person with a frown on their face a lot of the time? I always think that they are unhappy with their life. I read that smiling is a positive emotional reaction which indicates happiness, joy, love and affection. When you frown you are expressing negative emotional reactions like frustration, anger, fear, worry and anxiety. I love to see people smile! It's a simple thing to do and it's catchy. Try it some time!
