The phone vibrated. Across the table, her sister, Chloe, raised an eyebrow. The text, a stream of praise for Chloe's amazing support through a difficult time, was meant for her. Instead, it was sent to her critical and competitive younger sister, Emily. She braced herself. Then, a reply: *“Wow, that’s so nice of you. I’m truly impressed with how you’ve handled things."* She closed her eyes, and a slow smile spread across her face. This was a victory. This was more than she ever could have anticipated.

She immediately texted Chloe the correct message.
