I sleep when I feel like sleeping and get up when I feel like getting up. I have never slept on any regular schedule.
My father did something that used to be normal: he bought a lot and built a 1BR house on the back. The family lived in that while he built a real house on the front of the lot, all paid for, cash in fist or scrounged from construction sites. (That was legal in those days too.) So when my mother died, we had two houses with no mortgage. My brother took the big house and he pays the taxes and water/sewer, and I live in the little house with electricity my only expense and social security my only income.
So yeah, I find myself surfing the internet at odd hours.
Well it is 12:30 AM Sunday morning here on the Pacific raincoast of Washington State, and I am a person who has always loved the wee hours...just finished an hour of meditation, and checking in on aMug before a bath, cup of tea, and then sleep! (Maybe sleep...or maybe not)
