A girl with no smile

I know someone that never smile. Maybe she smile sometimes, but ever since I know her, I never seen her smile.

I wonder why. Maybe she is bored with her life? or maybe she got divorced so she can't smile anymore?

It's just ridiculous how she can keep her flat face all the time. And her face looks so old without a smile on her face. Nothing wrong with smiling unless you smile every second than you might consider crazy.
