Smiling Bloopers• Insincere smiling can backfire! (Different from a shy smile that just beckons a friendly hello.)• Transitioning from a smile to a straight face, too quickly, may give others the impression that you are fake or do not like them.• Going overboard and smiling all the time, especially when it is inappropriate, will make you appear insincere.• If your mouth smiles, but your eyes don’t, there is a disconnect that can make you appear less authentic and trustworthy.
