I will now blog without using a common graphic mark. (Hint: fifth in a row.) Wriiting without that sign won't work for long, probably. Doing without grammar parts (nouns say) is difficult. Doing without this visual sign is awkward and not particularly illuminating. Try doing it for six thousands words at a pop, as a task in a composition class. Good luck with that! Try for it not to sound awkward, with a smooth quality all its own, not just as a stunt for a blog post. As I thought, you can't do it. Hah!
