Wrote to my father this morning. Received after breakfast a most extraordinary letter from my Mother.1 What could possibly be the cause of such a singular break is beyond my comprehension. She informs me that it is doubtful whether John’s marriage ever takes place. All this is new and astonishing. She threatens to leave the house and much more which is a cause of incessant puzzle to me. Had much conversation with George upon the subject. He talks very rationally. At the Office but did not do much. My father seems to have a most singular concurrence of misfortunes to contend with at the present moment. In the afternoon I went to Mrs. P. C. Brooks Jr. in Chesnut Street to see Abby. She came in late. In the evening I went with her to the Wedding visit of Mrs. J. Quincy Jr. My spirits were not very high, and I saw much in Abby’s conduct this evening to displease me and to depress them still lower. Returned home very shortly.
