50 POINTS!! Can someone summarize chapter 16 of The Scarlet Letter?

As Chillingworth walks away, Hester goes to find Pearl. She realizes that, although it is a sin to do so, she hates her husband. If she once thought she was happy with him, it was only self-delusion. Pearl has been playing in the tide pools down on the beach. Pretending to be a mermaid, she puts eelgrass on her chest in the shape of an “A,” one that is “freshly green, instead of scarlet.” Pearl hopes that her mother will ask her about the letter, and Hester does inquire whether Pearl understands the meaning of the symbol on her mother’s chest. They proceed to discuss the meaning of the scarlet letter. Pearl connects the letter to Dimmesdale’s frequent habit of clutching his hand over his heart, and Hester is unnerved by her daughter’s perceptiveness. She realizes the child is too young to know the truth and decides not to explain the significance of the letter to her. Pearl is persistent, though, and for the next several days she harangues her mother about the letter and about the minister’s habit of reaching for his heart.
