A goof that I noticed...
Right after Vanessa cut her hair, she wanted to stay home from school, but her mother made her go. As soon as she got there, she ran off and spent the whole day just walking/running around, sitting under trees and killing time, etc... It was raining on and off all day, so in reality, Vanessa would have been a mess by the time she got into her mom's car at 3:00. Her hair would have been messed up, and she would have been all wet. She also ran all the way to the car, so she should have been out of breath, but she wasn't. When she got into the car, her hair looked just as clean and well-groomed as it was when she first was dropped off at school.
Just something I noticed...
