Hermione didn't know how she managed to keep Ron sane when she couldn't do the same for herself, but she appreciated the sentiment. "There's just so many things to work through at once," she muttered quietly. Not moving because of his request, she thought she really should be the one clearing the table and doing the dishes. He had been at work all day. But she knew even if she got up to help he wouldn't let her; they were both as stubborn as you could get.
So she waited until he was done and then standing beside her. Taking his hands as he pulled her to her feet, she wasn't entirely sure where 'come on' ended up.
