The idea of this new post motivates her to rectify her youthful omission, and she goes back to school in Montparnasse. Just before classes are to start, her current boyfriend's condescending ways prove too much for her, and she breaks up with him, reacting to that by getting drunk.

Fortunately, she meets an elderly man, a retired musician for the Paris Opera, who is headed for the very same destination. The two form a relationship of mutual encouragement and support.
