“Instead, I had to compose a letter. I could picture you reading the letter and I imagined you would do this slowly and carefully, so I felt I needed to write my letter to you slowly and carefully. I had to be sure I had read yours to Professor Glob slowly and carefully so that I could be sure to address the points you made. So we have gone on. We have written at length and thoughtfully, and to do this, we have both had to read the letters we received in a thoughtful way.”
