Coming home is Anna's favourite part of the day. It's warm and clean – not school or work. It's relaxing.
Plus, she's been thinking. Ever since that night at the bar. It's mostly faded to a dull memory now, but she does remember crying. Hugging Elsa and being hugged in return. She's never really had a friend she could call on like that.
It's why she doesn't mind driving Elsa places. Picking her up for appointments, or picking up food for cravings.
Now, Elsa's her best friend. And she is Elsa's.
