She could not finish the generous effusion

To this nest of comforts Fanny now walked down to try its influence on an agitated, doubting spirit, to see if by looking at Edmund's profile she could catch any of his counsel, or by giving air to her geraniums she might inhale a breeze of mental strength herself. But she had more than fears of her own perseverance to remove: she had begun to feel undecided as to what she _ought_ _to_ _do_; and as she walked round the room her doubts were increasing. Was she _right_ in refusing what was so warmly asked, so strongly wished for--what might be so essential to a scheme on which some of those to whom she owed the greatest complaisance had set their hearts? Was it not ill-nature, selfishness, and a fear of exposing herself? And would Edmund's judgment, would his persuasion of Sir Thomas's disapprobation of the whole, be enough to justify her in a determined denial in spite of all the rest? It would be so horrible to her to act that she was inclined to suspect the truth and purity of her own scruples; and as she looked around her, the claims of her cousins to being obliged were strengthened by the sight of present upon present that she had received from them. The table between the windows was covered with work-boxes and netting-boxes which had been given her at different times, principally by Tom; and she grew bewildered as to the amount of the debt which all these kind remembrances produced. A tap at the door roused her in the midst of this attempt to find her way to her duty, and her gentle "Come in" was answered by the appearance of one, before whom all her doubts were wont to be laid. Her eyes brightened at the sight of Edmund.
"Yes, your advice and opinion. I do not know what to do. This acting scheme gets worse and worse, you see. They have chosen almost as bad a play as they could, and now, to complete the business, are going to ask the help of a young man very slightly known to any of us. This is the end of all the privacy and propriety which was talked about at first. I know no harm of Charles Maddox; but the excessive intimacy which must spring from his being admitted among us in this manner is highly objectionable, the _more_ than intimacy--the familiarity. I cannot think of it with any patience; and it does appear to me an evil of such magnitude as must, _if_ _possible_, be prevented. Do not you see it in the same light?"
"But what? I see your judgment is not with me. Think it a little over. Perhaps you are not so much aware as I am of the mischief that _may_, of the unpleasantness that _must_ arise from a young man's being received in this manner: domesticated among us; authorised to come at all hours, and placed suddenly on a footing which must do away all restraints. To think only of the licence which every rehearsal must tend to create. It is all very bad! Put yourself in Miss Crawford's place, Fanny. Consider what it would be to act Amelia with a stranger. She has a right to be felt for, because she evidently feels for herself. I heard enough of what she said to you last night to understand her unwillingness to be acting with a stranger; and as she probably engaged in the part with different expectations--perhaps without considering the subject enough to know what was likely to be-- it would be ungenerous, it would be really wrong to expose her to it. Her feelings ought to be respected. Does it not strike you so, Fanny? You hesitate."
"I am sorry for Miss Crawford; but I am more sorry to see you drawn in to do what you had resolved against, and what you are known to think will be disagreeable to my uncle. It will be such a triumph to the others!"
"They will not have much cause of triumph when they see how infamously I act. But, however, triumph there certainly will be, and I must brave it. But if I can be the means of restraining the publicity of the business, of limiting the exhibition, of concentrating our folly, I shall be well repaid. As I am now, I have no influence, I can do nothing: I have offended them, and they will not hear me; but when I have put them in good-humour by this concession, I am not without hopes of persuading them to confine the representation within a much smaller circle than they are now in the high road for. This will be a material gain. My object is to confine it to Mrs. Rushworth and the Grants. Will not this be worth gaining?"
She could not finish the generous effusion. Her conscience stopt her in the middle, but Edmund was satisfied.
