Ooh it's a long time since I commented on this. I was thinking about this today actually!

I think a lot of it has to do with whether writing is your job, or your hobby.

As a dog groomer I always have Sundays off for church, and I try to keep it that way. I think it's important to have one day off work.

However, I would go for a countryside walk on a Sunday, my brother might go fishing for a while after church, as he finds it relaxing.

Which is why I would write on a Sunday, because for me it's a hobby and I find it relaxing. It's like walking in the countryside, or spending an hour fishing you know?

I think if it's your work, it makes it another kettle of fish, but as a hobby - it's not work.
