Before the Sims 3, Prudence was the oldest child of the Calvert. She lived in Sunset Valley. Her parents were Theopania Calvert, and Edmund Calvert. She was raised in a very old-fashioned setting and tended to do things the traditional way. Although as she got older she wanted more out of life and decided that she wanted to make some friends so she met Simon Crumplebottom. They played in their yard and had all sorts of fun. In the end Prudence ended up with Simon and they got married and had two kids. Later her daughters got married and Cornelia had Mortimer, and sadly, Agnes's husband died.
Secretly, she always wanted to become a doctor but she never got to live this dream because she had children.
