Thank you for your letter. I hope writing it made you feel better.  Probably I deceive myself when I write that I have learned to survive by writing. I hope the same for you. I am at fault. Not only "truth" but also "fault" is located "within", in "subjectivity". About the door, I will write to Nathaniel, and send you a copy, which you may read, if that seems best to you. I hope your day gets easier as time passes.  Another answer is BWV 146.
