Glad it's not just me. I can easily go weeks without doing any serious housework.....and the car has green stuff growing on it.
We have friends who are very structured:
Same meal each day of the week every week,
Same day every week for housework & gardening (weather dependant),
Same shopping day every week,
Cars cleaned every other week,
Holidays at same place on the same week every year.
Each to their own, of course. But not for us. Had enough structure during our careers!
