Sister Rivalry

   Fed up with your daughters' constant bickering? The ABC TV news show, 20/20 would like to step in and help.  New York or tri-state area families with at least two girls, ages 11-25 who live at home, are welcome to contact the show for a chance to be featured on camera and air their grievances.  Are they ridiculously competitive with each other, arguing about who's prettier or smarter, or who gets away with more? Is one sister constantly bossing the other one around? Has it reached the boiling point where no matter what you do as a parent, they just don't get along and you're worried that they might be estranged in the future? 20/20 will visit the selected family's home with their cameras, capturing all the bickering on tape.  Then, an expert who has studied the common problems that arise between sisters will offer tips on helping the girls to resolve their differences (or at least keep the peace). Boys are welcome too! To submit your story for the opportunity to be featured on-air, contact: http://abcnews.go.com/2020/story?id=7807653.
