sad eyes on smiling faces

working in retail provides a lot of people-observing which is something that this introverted person loves to do.  numerous people flood into the little store buying and returning and exchanging.  as someone who has always been a very strong observer, there's something I've noticed that I see in a lot of the customers that come and go...
there are so many sad eyes on smiling faces.  it's been a sad observation--  people with different fashions and lives and stories who smile to hide the pain of lost dreams, past pain, and sorrow.  people whose eyes tell the story.  I always smile back, offer a compliment and hope that somehow their day, their life will get better.  I sorta pride myself on my people-observing skills, but this has been one observation that has left me sad.
sad for those who fake a smile
for those whose dreams are lost
for those who walk around trying to hide the pain
for those who carry the weight of the world in one pair of eyes

eyes tell stories but some stories are sad to read.
