Hester comes to dread children because (a) they taunt her as she walks down the street, calling her ugly names.
Hester is the protagonist of the novel The Scarlett Letter, which was written by Nathaniel Hawthorne in 1850. Throughout the book, Hester is forced to wear an "A", the scarlett letter, on her clothes to indicate that she has committed adultery. As a result, she gives birth to Pearl, an illegitimate child, and she is forced to put up with public humiliation for the rest of her life. As this excerpt shows, even children mock her and insult her when she walks down the street for being a 'sinner'.
