I can please myself, I generally get up around 8 am-ish, get things ready for breakfast, lunch and tea, then wash and dress. I quite like having a routine of sorts but don't stick to it slavishly. I go to bed when I'm tired.
In-laws always liked their routines rigidly, used to ask me repeatedly what time I got up, ate, went to bed etc as if it was of utmost importance.
Years ago they went to stay with old school-friends who did as they pleased. The children (my DH and his brother) had a whale of a time with lots of freedom to go paddling, play in the fields, go fishing etc, come back to the house when they got hungry but MIL/FIL were absolutely horrified - and talked about it endlessly on their return home. If murder had taken place they couldn't have been more shocked.
