Constance McMillen, the Mississippi teen suing her high school over a ban on same-sex couples attending the prom, thought the worst might be over when the school agreed to a private dance to be held off school property. But when she and her date arrived at the Fulton Country Club on Friday night, they found only seven other students. "She didn't stay very long because of the sparse attendance," Kristy Bennett, her legal counsel, told msnbc.com. "We've heard there was another event out in the county," said Bennett, legal director for the Mississippi branch of the American Civil Liberties Union.
