Help on a quote please

[TN al]

My wife is an elementary school teacher in the south and wants to do a unit on famous Americans, including Ulysses Grant. She is from the north and I admit it, she is not above twisting the knife. Anyway she asked me about a quote from his memoirs and I have misplaced my copy of the book. The quote is early in the book when he describes his feelings about going to West Point. It is something along the lines of: "I did not think that I wanted to go to West Point but after talking to my father I found that I did." Could somebody please tell me the exact wording so that I can pass it on to her. You will be helping the education of untold tens of southern elementary school students. Thank you in advance.
