A smile is a pleasure
When you like someone
A smile is happiness
When you love someone
A smile is professional
When you are at work
A smile is grimace
When you dislike someone
A smile is anxiety
When you hate someone
A smile is spontaneous
When you see an old friend
A smile is contagious.
When is genuine.
A smile makes you real.
