Value of a dog

I know, I know. I'll stop doing Bruno blips after today.
But today I realised why I'd got a dog. I'm working at home, so start about 7.30ish. By 11 I wanted a break, so I drove to the bay, and we had a walk along the barrage. Now, if I was on my own, there's no way I'd drive for 15 minutes to do a half hour walk and then come back again. But it was a nice break, and just what I needed before back to more skype meetings.
James Clay wrote a neat post today about why people don't use learning technology, comparing it with the answer to "why don't I have a dog?"
