paraphrasing probably, I am in the smallest room in my house. I have your review in front of me. Now it is behind me" I have heard it is attributed to the composer Max Reger, to Winston Churchill, and to George Bernard Shaw, but not sure if any of these is correct.
Certainly the most celebrated use of it was a quotation from the German musician Max Reger. Reger was notoriously irascible and didn't react well to a savage review by Rudolph Louis in Münchener Neueste Nachrichten, February 1906. His response was:
"Ich sitze in dem kleinsten Zimmer in meinem Hause. Ich habe ihre Kritik vor mir. Im nachsten Augenblick wird sie hinter mir sein"
("I am sitting in the smallest room of my house. I have your review before me. In a moment it will be behind me!")
