The ruby girl

She dated a guy in the early fifties. The boy asked her to wear a red dress tomorrow and wait for him in "Ferdowsi square" in Tehran. "The ruby" put on shis red dress and appeared there at the hour. But that boy did not come. Ruby continued that for thirty years. Every day, she used to come on the same time in a red dress and wait for her love. Every day without exception!! Since the beginning of the eighties, no one has seen "ruby girl" anymore...
