Growing restless just sitting around the flat, Hermione had decided on the spur of the moment that she needed to get out. To where, she didn't actually know. Just out. Walking through Muggle London, she eventually ended up at her parents house, staying for around an hour before she headed home again.
Unlocking the front door upon her return, she closed it behind her, shrugging her coat off and hanging it up inside the door. Glancing at herself in the mirror as she did so, she noted the fact that her nose and cheeks were red from the cold and there were snowflakes caught in her hair. All part of walking the way back from her parents' house in lieu of apparating, seeing as there was no rush for her to get home anyway.
Somewhere close to frozen, Hermione took her gloves off and tucked them into the pocket of her coat. A hot shower and a cup of tea sounded wonderful just then.
After putting the kettle on, she went to retrieve her pyjamas, and flicking on the bedroom light was surprised to see Ron there in bed. She had been under the impression he wasn't coming home.
