Notes taken on a train are always a little better than notes taken at a desk. I do not know why. Perhaps it is the movement, perhaps it is the lack of anything else to do, perhaps it is just that a train window is a good place to think.
On this trip I wrote about the market I had visited that morning, the soup I had eaten the night before, and a walk I wanted to take when I got home. None of those notes became a plan. Most of them became, eventually, posts on this site.
That is how this notebook works, in the end. A day out, a few lines in a notebook, and later, a short post.
