The couple of days before her parents arrived passed smoothly. But as soon as they arrived, Sarah realized a major issue with the wishes making her younger, she was completely unable to answer simple questions about how her Freshman year went.
Her parents were clearly growing concerned, when she couldn't name her favorite class or talk about things she had studied. Feeling backed into a corner, she had no choice but to wish to remember what happened in her new reality. Which of course bumped her down to 18 and she found herself at freshmen orientation rather than packing up her dorm.
She was more than a little annoyed with this unwanted downgrade, but at least she now could remember things she had supposedly done properly. It also conveniently turned out the summer camp volunteer program was open to incoming freshman, though she wasn't sure if that was the case prior to her most recent wish.
After the slightly comical nature of a tour of a campus she had already spent four years on, Sarah was relieved to be done with her second orientation. On the way home, she did her best to sound appropriately enthusiastic about starting college and her parents thankfully didn't notice anything amiss this time.
