I am creating a list in an ng-repeat , I need to give all li elements who are the nth child of their father or more , a certain class (in our ng-repeat it means all children who have an index greater than middle) . For example , if the list is 10 items I need to give the 5th,6th...10th li children a class . So if my code is something this -

 [ul]
    [li  ng-repeat="friend in friends"]
       {{friend.name}} who is {{friend.age}} years old.
    [/li]
  [/ul]

What is a possible and good way to assign a class to the children from the middle index and above? My conditions are that I shouldn't change the structure of the html . I can add directives\filters or add things to controllers.
