Input: story: CHAPTER XII. 

Madame Colonna, with that vivacious energy which characterises the south, had no sooner seen Coningsby, and heard his praises celebrated by his grandfather, than she resolved that an alliance should sooner or later take place between him and her step-daughter. She imparted her projects without delay to Lucretia, who received them in a different spirit from that in which they were communicated. Lucretia bore as little resemblance to her step-mother in character, as in person. If she did not possess her beauty, she was born with an intellect of far greater capacity and reach. She had a deep judgment. A hasty alliance with a youth, arranged by their mutual relatives, might suit very well the clime and manners of Italy, but Lucretia was well aware that it was altogether opposed to the habits and feelings of this country. She had no conviction that either Coningsby would wish to marry her, or, if willing, that his grandfather would sanction such a step in one as yet only on the threshold of the world. Lucretia therefore received the suggestions and proposals of Madarne Colonna with coldness and indifference; one might even say contempt, for she neither felt respect for this lady, nor was she sedulous to evince it. Although really younger than Coningsby, Lucretia felt that a woman of eighteen is, in all worldly considerations, ten years older than a youth of the same age. She anticipated that a considerable time might elapse before Coningsby would feel it necessary to seal his destiny by marriage, while, on the other hand, she was not only anxious, but resolved, not to delay on her part her emancipation from the galling position in which she very frequently found herself. ', question: 'Who is she younger than?

eighteen
