Division of Self is a move from the Receptiveness Framework — naming two of your roles at once to de-escalate a hard conversation. Example: "As your daughter AND as your friend, I want to say..." This works because it reminds the other person that you hold multiple relationships with them simultaneously, making it harder to flatten you into a single adversarial role. It's one of the concrete linguistic tactics Julia Minson, Hanne Collins, and Mike Yeomans have shown to raise receptiveness in disagreement.
