Later love (Eliot)

How is it that the poets have said so many fine things about our first love, so few about our later love? Are their first poems their best? or are not those the best which come from their fuller thought, their larger experience, their deeper-rooted affections? The boy’s flute-like voice has its own spring charm; but the man should yield a richer, deeper music.

George Eliot, Adam Bede
