You see she does not like to act.

Let her chuse for herself, as well as the rest of us.

Her judgment may be quite as safely trusted.

Do not urge her any more." "I am not going to urge her," replied Mrs.Norris sharply; "but I shall think her a very obstinate, ungrateful girl, if she does not do what her aunt and cousins wish her--very ungrateful, indeed, considering who and what she is." Edmund was too angry to speak; but Miss Crawford, looking for a moment with astonished eyes at Mrs.Norris, and then at Fanny, whose tears were beginning to shew themselves, immediately said, with some keenness, "I do not like my situation: this _place_ is too hot for me," and moved away her chair to the opposite side of the table, close to Fanny, saying to her, in a kind, low whisper, as she placed herself, "Never mind, my dear Miss Price, this is a cross evening: everybody is cross and teasing, but do not let us mind them"; and with pointed attention continued to talk to her and endeavour to raise her spirits, in spite of being out of spirits herself.

By a look at her brother she prevented any farther entreaty from the theatrical board, and the really good feelings by which she was almost purely governed were rapidly restoring her to all the little she had lost in Edmund's favour.
Fanny did not love Miss Crawford; but she felt very much obliged to her for her present kindness; and when, from taking notice of her work, and wishing _she_ could work as well, and begging for the pattern, and supposing Fanny was now preparing for her _appearance_, as of course she would come out when her cousin was married, Miss Crawford proceeded to inquire if she had heard lately from her brother at sea, and said that she had quite a curiosity to see him, and imagined him a very fine young man, and advised Fanny to get his picture drawn before he went to sea again--she could not help admitting it to be very agreeable flattery, or help listening, and answering with more animation than she had intended.
The consultation upon the play still went on, and Miss Crawford's attention was first called from Fanny by Tom Bertram's telling her, with infinite regret, that he found it absolutely impossible for him to undertake the part of Anhalt in addition to the Butler: he had been most anxiously trying to make it out to be feasible, but it would not do; he must give it up.
