Context

“This reminds me that I have sometimes dreamed of writing a book on Saint Périne. Champfleury has treated this subject very badly. I see nothing whatever in it of a comical nature; I should bring out its painful and lamentable character. I believe that the heart never grows old; there are people in whom it even grows stronger with age. I was drier and harsher at twenty than I am to-day. I have become softened and feminised by wear and tear, while others have hardened and withered, and that almost makes me indignant. I feel that I am becoming a cow!” source
