+steps:
+  - headline: Identify the stimulus
+    description: >-
+      Before speaking, the person identifies the specific thing they observed
+      — what they saw or heard, separate from any judgement about it.
+  - headline: State without evaluation
+    description: >-
+      They articulate the observation as a factual statement: "When I saw the
+      dishes left on the table after dinner..." rather than "When you were
+      inconsiderate..."
+  - headline: Invite confirmation
+    description: >-
+      The speaker can invite the other person's view of the same observation,
+      allowing shared ground before moving to feelings and needs.
+outcome: >-
+  The conversation begins from a shared, non-judgemental description rather
+  than from accusation, reducing defensiveness.
+practice: >-
+  Practice distinguishing observation from evaluation — "you were late" is
+  often an evaluation. "We agreed to meet at seven; you arrived at seven
+  twenty" is an observation.
