My girlfriend is insistent that R2D2 is C3PO's pet

She says it is because R2D2 is smaller than C3PO and she will not listen to reason. She also says C3PO is always correcting R2D2's behavior, R2D2 doesn't talk and R2D2 is always following around C3PO like a pet. How should I proceed? via /r/StarWars https://ift.tt/2KJSuuF
