Dan can Dance

But not quite yet... My colleague has been off work for the last two weeks after a knee operation. He's been working from home for a big bit of it (thank the gods, I'd be completely fuxxed if he wasn't) but today he turned up for the afternoon - on crutches. He seemed to appreciate my present of a large screw, just in case he needed it for his knee. By the end of the day the tide had receded, over the horizon quickly. I wonder where its gone?
