‘As busy as I want to be, thanks,’ would be my reply. After a very busy weekend I had a lovely lazy day yesterday - I enjoy plenty of those now.
One thing I never thought when approaching retirement, over 10 years ago now, was, ‘Oh, good - I’ll have plenty of time for all the cleaning I don’t usually do!’
I’ve always had a bit of an anti-thing for those people who tell you they haven’t sat down all day, as if it was some sort of virtue. I particularly remember one such (a SAHP!) who invariably met me at the door with a duster or damp cloth in her hand, for the endless wiping of surfaces, and a sigh of martyr-ish exhaustion.
