Footprints ...

People-watching on public transit is always fun.  As this mother and son enjoyed what seemed to be their first ride on Metro, I enjoyed a running dialogue in my head about the footprint tattoos up her back.  No matter the scenario, my mind always ended at "... it was then I carried you." 

Perhaps, as suggested by a friend, she wears the tattoo to honor a lost child.  If so, my heart is with her.
