I ended up working later than planned.
Then it was time for DIY. I started sanding some radiators and moved on to painting them and then the skirting board in my upstairs room. I had Bleak Expectations series 2 playing - first time I'd heard it - it was my latest CD delivery. Very good.
When I came to dispose of my brush, it turned out to be after 2. The night had just flown by. Progress was made.
