I am mere glass

 Clear blue crystal

Fragile

Strong

 Unbreakable when hit with blunt force

 Shattered when sharp points are made

 Clear fragments of broken men

 Lay across the ground

  Shattered 

 By

  Everyone

  I am one of many

  I am already glass

 Already broken

Already shattered

Already unbreakable

 You cant blow me

Down
