She was very ungrateful and took everything for granted. She was also very lazy at home even if she has a job. Instead of acting like the boys' mother, she stepped back and let Patricia do the parenting. Her son Jordon knew that she doesn't care.
She is notable for her rude, impatient behavior when Jo took her to visit a local homeless shelter. In spite of Candace Sherwood's efforts to make her more appreciative, she didn't understand why Jo thought this was a good idea, and thought it was a waste of time.

She was 25 years old at the time at her appearance at Supernanny. She is now 33 years old in 2017.
