I'm afraid that since retiring I have become a bit like Violet, Dowager Duchess Grantham, who upon hearing someone saying they would come on the weekend, asked, "What's a weekend?". I know the feeling, for retirement means every day is the weekend, though for some reason, I can't imagine why, Saturday and Sunday are noisier than other days.
We actually don't do as much on Saturday and Sunday, we generally wait for other folks to go back to work so we can have places to ourselves.
I can remember loving to sleep late on the weekend and now I have the luxury of sleeping late every day, and I've got to tell you that I haven't gotten tired of that yet. I love not waking up to an alarm clock. I don't rush around on Saturday doing laundry, cleaning house, grocery shopping and then Sunday starting to get ready for the work week again. Saturday and Sunday are just 2 more days to do exactly what I want.
