When Lizzy doesn't want to go to Pemberley, for understandable reasons, why doesn't she say so? I've always been puzzled by this. She seems to place complete trust in her aunt in other matters. Even if she didn't want to tell about the rejected proposal, why didn't she say something to the point of, "As I am, however slightly, acquainted with Mr Darcy, I should feel wrong to go without being invited." In fact, why didn't the Gardeners consider this in the first place?
