Is it normal to rarely smile?
Mostly.Normal for most people
Yes. Some people naturally smile less than others, and a serious-looking face doesn’t mean you’re unhappy or unfriendly.
People differ in how expressive they are. Your personality, habits, culture, or simply how your face rests can all mean you smile less—and plenty of people aren’t big smilers.
Smiling isn’t a reliable measure of how happy or warm you are. If you’re asking because you’ve stopped smiling after a noticeable change in your mood or enjoyment of things, that’s worth paying attention to; otherwise, you don’t need to force a grin for anyone.
