Stretching out her fingers hit the edges of her bed, how long had it been since she last did this, just lay there in bed and not worried about the time? It was so wonderful, just her and her thoughts. No-one was going to hammer on her door and demand she get up, telling her that 'it's an emergency' on something that didn't even require her attention.
Rolling over, Tsunade contemplated her activities for the day. Getting up around midday, maybe. She could make some lunch easily, then in the afternoon . . . Eh that was free for her to do as she pleased. Maybe she would read a book while she drank some saké. She didn't really have any responsibilities so it didn't matter.
She really should have gotten round to this whole 'retirement' thing a lot sooner.
