Stick to what happened today. Dragging in last year turns a fix into a fight.

One problem can be solved. A pattern cannot be solved in a single conversation, and the moment you reach back for evidence from months ago you have changed the subject from a thing that went wrong to a case about who somebody is. Nobody repairs anything while being prosecuted. The old material usually surfaces because today’s complaint feels too small to justify how upset you are, which is the part worth saying instead.

Keep the next hard conversation inside one example and one request. If the older material still matters once today’s is settled, raise it separately and on purpose. Notice how much faster it goes.
