What are some of the things Mrs. Sparsit does in Book 2 to endear herself to Mr. Bounderby? Why does she do these things?

Mrs. Sparsit becomes a prowling snoop, keeping tabs on the affairs of the house. She is more and more resentful of Mr. Bounderby and seems to enjoy the fact that he is under more stress and his marriage is falling apart. At the same time, she hypocritically coddles and pampers Mr. Bounderby who only comes to resent Louisa even more, for lacking the domestic charms and offices of Mrs. Sparsit.
