✔ 最佳答案
She's practicing an audition line. Because
1. Her name is Vanessa, instead of Jennifer.
2. Her mom forgot the lines, then Vanessa reminded her. If it was a real conversation, her mom wouldn't need any remind.
3. During the audition, Vanessa repeated what she said in the car. If it was a real conversation, she didn't need to repeat it in the audition.
