When Pinkie Pie's parents die, she sends out letters to all of her sisters for the funeral. But when none of them RSVP she gets her sisters together to talk things out. When Pinkie Pie moved to Ponyville she didn't leave the rock farm on good hoofs. Maud was the only one who was able to forgive her. Pinkie really wants her sisters to pay their parents there respect, even if it means that she won't be able to.
