"Dear Audrey,
      I'm sure you've heard all about 9/11 at school, and how that day changed everyone's lives - especially those at Ground Zero.  But did you know that after 9/11 shrines to commemorate the fallen heroes started popping up all over the place like this one? Right after 9/11 someone put a fireman's hat on this rock, and next thing you know there were flowers, plants, flags and all kinds of things around it.  To this day, 10 years later, you can still find these shrines on the anniversary of 9/11.
      Love,
          Auntie"
