Okay, so started at 10AM. But did works through till gone three. Walked the dog. Was debating about going for a run, but the weather has been awful, so rang up and enquired about Spin, no problem with availability there. Did a few more hours and then went to Spin. Fairly exhausting. Came back and did another hour. All on CPU stuff. Then on with music practice, going quite well. Lang Ling or whatever his name is, has nothing to worry about. Got an email about doors, will be delivered on Monday.
