"That is just what I was going to say," added his wife.
Catherine, relieved for herself, felt uneasy for Isabella, and after a moment's thought, asked Mr. Allen whether it would not be both proper and kind in her to write to Miss Thorpe, and explain the indecorum of which she must be as insensible as herself; for she considered that Isabella might otherwise perhaps be going to Clifton the next day, in spite of what had passed. Mr. Allen, however, discouraged her from doing any such thing. "You had better leave her alone, my dear; she is old enough to know what she is about, and if not, has a mother to advise her. Mrs. Thorpe is too indulgent beyond a doubt; but, however, you had better not interfere. She and your brother choose to go, and you will be only getting ill will."
Catherine submitted, and though sorry to think that Isabella should be doing wrong, felt greatly relieved by Mr. Allen's approbation of her own conduct, and truly rejoiced to be preserved by his advice from the danger of falling into such an error herself. Her escape from being one of the party to Clifton was now an escape indeed; for what would the Tilneys have thought of her, if she had broken her promise to them in order to do what was wrong in itself, if she had been guilty of one breach of propriety, only to enable her to be guilty of another?
