I did lots of housework nice and early so that I could go up to Tate Britain later. I saw the Edward Burne Jones and watched a couple of the Turner Prize films. Then Keith arrived and we had cake and a cuppa, (the hugest slice of carrot cake for me). We watched two of the Turner Prize films before we walked through some of the more recent "Ages". We had a sit in the Martin Creed Don't Worry room with lots of metronomes.
It was very dark by the time I walked back over Vauxhall Bridge, and then the trains home were very crowded, but I managed to get a seat.
The carrot cake sustained me, I did not need dinner, just a slice of toast and marmite.
