In the quote by Jean Anouilh, there is a reflection on solitude and the nature of love. It suggests that the journey of life is often experienced alone, and true love remains a personal affair, never fully shared with others. This highlights a sense of isolation that can accompany aging, as wisdom gained over the years leads to a realization of one's solitary path.

The mention of the sage and gray hair points to the wisdom and understanding that come with age, yet also emphasizes the difficulty of accepting loneliness. It underscores that, despite the emotional complexities of love, it can ultimately leave individuals feeling isolated as they navigate life on their own.
