Hermione could move through a house swiftly when necessary. After every room had been examined for anything that could be taken, she helped herself to a meal of whatever she could find left in the kitchen. She had to save the jars and cans in her bag for the days she wasn't able to steal a good meal. Unfortunately, there were generally more of those days than there were of the other. When she was past satiated and on the verge of being too full to move, she headed back down the stairs to retrieve her blankets. It was best to get out of the house as quickly as she could. Hiding in houses in the daytime had an extra set of dangers.
