Well it would be a very good thing--I mean to restore the friendship, but they went too far, said a lot of bad things to each other and for each other, so I think a reunion or even the restore of their friendship is something very unreal.
When you finish a friendship, arguing and insulting your ex-friends, saying it publicly ...and try to return to it someday-- (if it happen) --it will be always very different, cause you think you can restore the feelings, but you can't. It's not the same thing.
