Anna looked up and turned off the music.
"What's up, Elsa?"
Elsa was holding a plain notebook. It looked vaguely familiar, but Anna had collected a lot of notebooks over the years, and sometimes couldn't remember which was which, not right away.
"I was doing some organizing, I hope you don't mind," Elsa began to explain.
"Of course I don't mind," Anna insisted. "Find anything good?"
"I… I found something interesting?"
"Oh!" Anna exclaimed. "Is that one of my old notebooks?"
"Yeah… I started looking through it, I'm sorry, but…"
"I remember now! The monsters in the crop tops?"
