I spend alot of time in solitude since my retirement and my choice is to go camping in my camper to deserts and mountains. I like to practice sumi-e brush painting and am beginning some watercolor disciplines.
Although I knew this was an "S" motion, I wanted to make it in the horizontal position hence, more of an "N". It was raining outside my camper that day and I then did a whole series of brushwork with rain drops. I liked doing things like that.
