Agree with all that's been said except for Wilfried's unfortunate attribution of anthropomorphic properties to the nightingale he heard. How did he know it was singing about "love and lust"? It might have been the usual morning grumbles about hunger or constipation, for all we know - just because it sounds pretty it doesn't make its contents so.

In fact, the thought of humans saying sweet nothings to each other as they listen to a bird moan about last night's meal rather appeals to me...
