Carrie didn't smoke. She didn't drink. She didn't have pets or a boyfriend. She loved to cook and she had a steady job. Carrie was an O.P. — an organisational professional. She helped arrange people's lives for them. She owned her own car. Her parents lived out of town. She believed toothpaste belonged on a brush and not in the sink.
Carrie ended up being O.C.D., rearranging everything in the house, which got on Rhonda's nerves. After it became too much, Rhonda asked Carrie to move out, which she did gladly.
Carrie returned later in the season when Rhonda was planning her wedding to Terrence Haggard. Terrence was more welcoming of Carrie than Rhonda, so much so that they hired her to plan their wedding. Rhonda was convinced Carrie was coming after Terrence, but Terrence wasn't interested in Carrie.
