Smile = Happiness?

Have you not seen the villains in the movie smile just before killing? Smile comes off happiness, but if somebody is smiling that does not mean he is happy. He might be hiding his sadness.

Up to now we all are agree that smile necessarily does not mean happiness. Smiling is a gesture, having so many problem a person can keep smiling face it does not matter. Happiness is such that comes from inside a person there must be a lot more non-verbal signs from a real happy person that we could easily notice.

Nop, a smiling person is not always a happy person. Sometimes those that smile the most are those that are more broken and depressed. A smile is usually something we hide behind so other wont go asking what are problems are. And this way we dont have to remember the sad things in life.

Not all the time. Because as for me, I easily see if the person's smile is a genuine one or he/she just needs to smile because the situation needs him/her to.
