Donna is not Brenda's friend
Sometimes I read that Brenda's only friend was Donna but I don't agree. Donna didn't really care when Kelly takes up with Dylan. She only made a speech at the Peach Pit because Brenda and Kelly's fighting was annoying her. Also when Brenda and Kelly try for the play Donna doesn't care that once again Kelly is about to horn in on the lead and even gives her a present. Donna might have been sweet but her loyalties were with Kelly not Brenda. When Brenda comforts Donna when she catches David, Brenda was being an amazing friend but it was to someone who did not comfort her when she was distraught about Dylan and Kelly. Brenda becomes depressed and withdrawn after Dylan basically falls out of love with her and decides he needs to do Kelly. It would have been nice if Donna wasn't constantly acting so nonchalant about Kelly taking Brenda's man. Just had to rant this.
