Is it normal to never smile?
In most cases, I never smile. It's not that I can't, or refuse not to, it's just something I don't naturally do. Even on a good day, talking to a good buddy or family member, I don't smile. A joke can get me to chuckle, but it's not like it glues a smile on my face for the next 10 minutes. The more I see people who smile the more abnormal I feel.
