The streak of white in Anna's red hair was hard for Elsa to miss. For a moment she didn't even move, just stood still and stared at her sister, contemplating the change in her. A bright grin was on her sister's face, and her blue eyes sparkled.
"So," Anna said turning slightly to show off her white streak even more. "What do you think?"
Elsa wanted to reply that she was glad that the bathroom hadn't been destroyed, if not at least eternally stained, while Anna had messed with hair dye.
"It doesn't make me look old, does it?" Anna winked.
Else couldn't help but chuckle. "Oh no, it's not that."
Anna's eyes widened. "Do you like it?"
Elsa nodded, yet still raised an eyebrow. "Why white?"
Her reckless, headstrong sister seemed like the type who would get something pink or blue or purple (or even black, considering that was the only color she consistently wore). White was the last color Elsa would have expected.
"Of course I chose white," Anna said with a smile. "I got it to remind me of you."
