Around 5:30 pm this afternoon my wife and I brought Derek back to his home. He is quite tired at this time but no doubt happy to be away from the hospital (no reflection on the great staff there!). He had a big day, visiting his friend Simon and dealing with the minutiae which go with hospital discharge. He even managed to walk up one flight of stairs at the hospital and did it again at home. We are all happy to see him back with his family. Airdrie and the kids prepared the house for him and got everything ready so that he'll be comfortable in his recovery.
I'm not sure when Derek will "reappear" on his blog, but since it does not require a lot of physical exertion, I expect that you'll hear from him directly sooner rather than later.
