Arizona sighed as she walked out of the OR. Surgery was exciting, it was true, but sometimes it was also stressful and hard. Working on a case with Cristina and Owen would not rank anywhere near her most enjoyable surgeries. Between them hardly talking to other except about the surgery, interspersed with the meaningful glances they traded every time Sofia came up (which was a lot! Arizona liked to talk about her baby!) it had not been a fun operation.

Taking a few quick steps to build up speed, Arizona rolled down the hall on her heelies. The one perk of finishing a surgery late: No people around meant more room for her to use her heelie sneakers. She stopped at the nurses station and grabbed her patient chart, filling it out as quickly as she could while still being thorough.

"How was your day, Dr. Robbins?" the nurse asked.

"Long," Arizona answered. "How was yours."

The nurse shook her head. "I hate winter drivers," she said.

Arizona chuckled slightly as she finished filling out the chart and slotted it back into place. "I'm heading home for the night," she said. "Merry Christmas."

"Merry Christmas," the nurse echoed back.

Stopping in the changing room to switch out her lab coat for her regular clothes, Arizona stepped out into the lobby. It's been a long day, she mused. It usually didn't bother her, but between Owen and Cristina in surgery today, the fact that her and Callie had been on opposite shifts for a week, and her long days at work recently, she was tired.

She hadn't even had a chance to enjoy the holidays yet. No decorations were up (except for in the hospital, where she'd inexplicably run into some mistletoe in an on-call room), and her and Callie hadn't even had the chance to go on one date in December yet.

Not that she cared, exactly. Working in a hospital meant no one really got a chance to fully enjoy the holidays (except for the aforementioned mistletoe. She blamed Karev for that one) and there definitely wasn't the same amount of ridiculous marketing as there would be literally anywhere else.

Still, Arizona decided that if she couldn't get her hands on something Christmassy in the next few days she might as well pretend like December wasn't happening this year.

"Arizona!"

Hearing her name, Arizona looked up. Callie was standing across the lobby waving. She was wearing her usual coat, red mittens and a green scarf with snowflakes embroidered on it.

"What are you doing here?" Arizona asked, hurrying towards her wife. "I'm so glad to see you, but I thought you and I were on opposite schedules."

Callie smiled at her. "Owen shuffled the schedules. I think he just doesn't want to work with Cristina right now, but don't let him know I told you."

Arizona shrugged. "Works for me," she said. "Besides, now we have more time to ourselves."

"Dr. Robbins, are you trying to seduce me?" Callie asked, lowering her voice slightly.

"Maybe," Arizona smiled at her.

"I thought so," Callie answered, returning the look Arizona was giving her. "Anyway, is there anything you'd like to do? Meredith and Derek took Sofia for a playdate – apparently Zola needs to meet up with friends outside of daycare."

Arizona thought for a moment. "I can think of lots of things I'd like to do with you...and to you." She paused, looking Callie up and down. "Right now, though, I just have one thing I want."

"You're right!" Callie said as they walked through the park arm in arm.

Arizona grinned, looking up at the few stars she could see in the sky. "Told you hot chocolate was the perfect idea for a date night."

"And the marshmallows!" Callie looked through the hole in the lid of her cup. "Are they shaped like stars?"

Nodding, Arizona took another sip. "It tastes better like that," she said. "Or at least, that's what my brother told me when we were kids." She sighed. "I wish he could be here right now; seeing the family for Christmas was one of the high points of his year."

Callie put her arm through Arizona's. "Do you want to tell me about how you guys celebrated?" she asked.

"Yeah, I think I would," Arizona said with a small smile. For the next half-hour, she told Callie about Christmas at her house when she was growing up: the way her brother would always joke about what sort of decorating scheme to use on the tree when they always used the same one, how her dad would make hot chocolate and her brother's joke about the marshmallows eventually extended to the whole family, about her mom always waiting until Christmas Eve to wrap her dad's presents because of the time he'd looked at all of them before re-wrapping them, and all the other little stories and traditions her family had accumulated through the years.

When she had finished, she looked over to see Callie smiling. "I think all of that sounds really cool."

Arizona smiled, taking a last sip of her hot chocolate. "And now I'm a surgeon with no time for any of that," she said without bitterness.

Callie shrugged. "We can figure out new things to do with Sofia," she said. "Isn't that what having your own family is about? Figuring what we want to carry on or leave behind from out family traditions?"

Arizona laughed. "Yeah, I guess it is," she said. She paused for a moment, considering. "Like the mistletoe in the on-call room."

Callie raised an eyebrow. "You think that's a good idea?" She leaned closer to Arizona. "Because I can tell you right now, I don't need a reason to kiss you."

"Neither do I," Arizona answered, leaning in to close the gap.

The kiss tasted like chocolate and marshmallow.
