One day the air was mild, the Luxembourg was flooded with sun and shade, the sky was as pure as if angels had rinsed it that morning, the sparrows were twittering deep in the chestnut trees, Marius had opened his whole soul to nature, he was not thinking anything, he lived and breathed, he passed close by the bench, the young girl glanced up at him and their eyes met. What was there this time in the young girl's gaze? Marius could not have said. It was nothing and everything. It was a strange lightning flash. She dropped her gaze and he went on his way.
