I've noticed ever since I start being conscious of how I communicate with my face and smiling more my boss started treated me differently. She's more happy around me and even tries being more playful with work related humor. Before it was just down to business, "let get this done" kind of relationship.

This isn't a "hey, i'm thinking of hitting on my boss" post because it's not (I would NEVER do that). I normally have a very serious and intimidating face, so ever since I started focusing on smiling more I see some changes on how people treat me.

How important would you say smiling is in communication in general?
