Hai,
Your smile is a messenger of your goodwill and brightens the lives of all who see it. To someone who has seen a dozen people frown, scowl or turn their faces away, your smile is like the sun breaking through the clouds!
According to Gandhiji " you are never dressed properly till you wear a smile " and " A smile is a gently curved line that sets a lot of things straight" .
Cheers
