A smile can have a hidden meaning for a crafty person. “There is a smile called the ‘Duping’ smile or ‘Dupper’s Delight’ which is typically a little smile that comes across the face when a liar or deal-maker or cheating-winner thinks they have duped someone,” explains body language expert, Patti Wood. Another tool to decipher a gloating smile is that the smile may be a mismatch for the other person or people you are with so they feel left out and less than, she says.
You’re full of joy
Wood describes a ‘laughing smile’ as when the mouth is open upper and lower teeth showing. This comfortable and inviting face exudes joy and sincerity. “The head is usually thrown back,” adds Wood.
You want to put people at ease
Everyone wants to be a smooth socialiser – which is why you may want to improve your social interaction skills. Smiling helps too: there is a lot of evidence of body language mirroring, according to an article in Psychology Today. “We automatically copy the facial expressions of others. We reciprocate and in social groups it can be contagious. People respond to, and evaluate, those who smile differently and more positively than those who do not.”
