The evil characters are balanced by the good characters, such as "Peggotty" – the faithful servant of the Copperfield family and a lifelong companion to David. Others include David's aunt "Betsy Trotwood" and her friend "Mr. Dick". "Agnes Wickfield" is a close friend of David since childhood, and later becomes David's second wife and mother of their children. "Mr. Micawber" is a gentle and friendly man who goes to debtors' prison, but in the end makes a success as a sheep farmer in Australia. He is based on Dickens's own father.
