A little girl wrote a heartbreaking response to her friend's invitation.

Ten-year-old Harmony Jones of Memphis, TN invited all of her friends from school to her birthday party. One girl from her class said she couldn't come, explaining in her note: "my dad will not let me go because you are black." Despite the adorable multicolored letters, that still must have stung.

Memphis is a city with a troubled history of racial conflict. Famously, Memphis's Lorraine Motel was the site of Martin Luther King Jr.'s assassination in 1968. The city's Health Sciences Park (formerly Forrest Park) still contains a statue of Nathan Bedford Forrest, the Confederate general who was also the first Grand Wizard of the Ku Klux Klan.
