Victor Hugo could not promise without keeping his word. He was not like me: I promise everything with the firm intention of keeping my promises, and two hours after I have forgotten all about them. If any one reminds me of what I have promised, I tear my hair, and to make up for my forgetfulness I say anything, I buy presents — in fact, I complicate my life with useless worries. It has always been thus, and always will be so.
Ch. 25 - My Double Life (1907)
