In chapter 17, Elizabeth realizes that Mr. Collins attentions to her are more than just politeness. "[I]t was not long before her mother gave her to understand that the probability of their marriage was exceedingly agreeable to her. Elizabeth, however, did not choose to take the hint, being well aware that a serious dispute must be the consequence of any reply." I can understand why she wouldn't tell her mother that she wasn't interest, but why didn't she approach her father on the subject? She could have asked him to inform Mr. Collins that his interests would be better suited in another direction or that he would not consent to them being together. Would this not be something Elizabeth could talk to her father about? Or did she need to wait until an offer was made to indicate her refusal?
