To be guided by second-hand conjecture is pitiful.

The premises are before you.

My brother is a lively and perhaps sometimes a thoughtless young man; he has had about a week's acquaintance with your friend, and he has known her engagement almost as long as he has known her." "Well," said Catherine, after some moments' consideration, "you may be able to guess at your brother's intentions from all this; but I am sure I cannot.

But is not your father uncomfortable about it?
Does not he want Captain Tilney to go away?
Sure, if your father were to speak to him, he would go." "My dear Miss Morland," said Henry, "in this amiable solicitude for your brother's comfort, may you not be a little mistaken?
Are you not carried a little too far?
Would he thank you, either on his own account or Miss Thorpe's, for supposing that her affection, or at least her good behaviour, is only to be secured by her seeing nothing of Captain Tilney?
Is he safe only in solitude?
Or is her heart constant to him only when unsolicited by anyone else?
He cannot think this--and you may be sure that he would not have you think it.

I will not say, 'Do not be uneasy,' because I know that you are so, at this moment; but be as little uneasy as you can.
