"My very worst worries are Rudolf’s tours, they are killing us both. If only we could get along without lecture-tours we would both be happy. But alas, how should we exist? I don’t know how it was at your time here, now lecture tours are physical and mainly mental torture. Rudolf simply loaths it and he is the most miserable man in the world when he is on route. He never enjoyed speaking, but worst of all when he has to lecture in Yiddish or English. The tour begun very miserably, his mood is simply terrible. He was happy at his work, he lived in it, got young once more, and it was a pleasue to see him at his desk. Now he had to put it aside and take up work which instead of being a pleasure is a physical and mental torture, so you can imagine how he must feel."
