This so perfectly describes my experience writing. When I have a story in my head it just shows up and I must get it down before I lose it forever. I often find myself searching for a pen and anything to write on. It’ll drive Danny crazy when I say I’m on my way to bed but show up an hour later because I have to write my thoughts down. I use to think it I was crazy (maybe I am) but now I think it might be the creative process.
