Chapter 17
Quote
The godparents arrived at the Faulkner townhouse while Mrs Bennet was busy preparing the list of items for the trousseaux and insisted they would pay for everything associated with their goddaughters’ trousseaux. In spite of all the protests Mr and Mrs Bennet made over the offer, Jane’s and Elizabeth’s godparents stood firm in their insistence that they would foot the cost of the items. They protested they had never been allowed to spoil the sisters with monetary gifts they could easily afford.
