Elizabeth, feeling all the more than common awkwardness and anxiety of his situation, now forced herself to speak; and immediately, though not very fluently, gave him to understand, that her sentiments had undergone so material a change, since the period to which he alluded, as to make her receive with gratitude and pleasure his present assurances. The happiness which this reply produced was such as he had probably never felt before; and he expressed himself on the occasion, as sensibly and as warmly as a man violently in love can be supposed to do."
