Callie could hear Arizona's steady breathing next to her, along with the occasional soft snoring. Not that Arizona would ever admit to it. Callie had brought it up one time and Arizona's vehement denial followed by a death glare that would make Bailey run for the hills made Callie vow to herself never to do it again. It didn't really matter, Callie was a heavy sleeper. Once she was down, not even an orchestra of trumpets and French horns could wake her up. She wondered if Arizona plays an instrument. Callie narrowed her eyes as she realized that there was so much she didn't know about her girlfriend. So much she still had to learn. There was one thing she knew though. One thing she was certain of. Arizona loves her. And she loves Arizona. Nothing else mattered. They have a lifetime to learn everything there is to know about each other. And with that thought, Callie smiled and snuggled closer to Arizona. Her smile turned into a full out chuckle when Arizona let out a particularly loud snore when Callie moved against her. Yes, Callie could sleep through anything. Unfortunately, she wasn't asleep yet.
