Smile Quote No. 21: A Smile is a Light in the Window of Your Face that Lets People Know You’re at Home
A smile is an expression of how you feel at any point in time when you react to a set of circumstances. If you are in a crowd or at work with colleagues they will know you are really part of their group if you respond to other people’s words. Listening but trying not to smile because you have noticeable gaps between your teeth makes you stand outside the group. When something humorous is said and you are afraid to react, then your group contact is lost.
