about eight o’clock
Francesca looked so lovely by candle-light that first evening that she shed a ray of brightness on his grieving heart . Her smiles flung the roses of hope on his woe . She sang , not indeed gay songs , but grave and solemn melodies suited to the state of Rodolphe 's heart , and he observed this touching care . At about eight o'clock the old man left the young people without any sign of uneasiness , and went to his room . When Francesca was tired of singing , she led Rodolphe on to the balcony , whence they perceived the sublime scenery of the lake , and signed to him to be seated by her on a rustic wooden bench . `` Am I very indiscreet in asking how old you are , cara Francesca ? '' said Rodolphe .
