Mrs. Bennet doesn't need someone else stirring her up to get going. She goes on her own anyway!!If not one moment than the next! Maybe she's wired that way. (I know a couple of people who seem to be! Other people can set them off, both purposely and inadvertently...so can the weather, the pets, the telephone, the mailman, a neighbor driving by....you name it!) I think Mrs. B stirs herself up just fine, and yes, the family would be better off without her agitations....but are stuck with them! We have varying degrees of tolerances for different things, you and I, but I daresay we can agree that we would not either one of us want to live in that household!
