The thing with dogs is you have to get up everyday. That's evryday, even if your Friday night entailed staying up carving out new plans for the world. I could so do with a lie in. But this is why work protects against depression. It's not because of the days when you're raring to get at it, it's those grey rainy days when you don't realy want to go in but you drag yourself there. That's where works anti depressant qualities come in.
