Hi Sarah- Editing it out of the file might be a biggie for your doc, but placing a clarifying note reflecting that it was a historical comment so perspective is gained by any other reader may be a mid point for you both that you can reach. I can't say I have appreciated every last word that was written, such as one doc who declined to treat me referring to my profession in his letter to the file.... it was wholly irrelevant but a part of the file nevertheless.

Oh well.... I hope you and your doc can reach a point where you feel at peace about this.

Prayers,
