I'm not sure where my current obsession has come from, but I LOVE writing short shorts. Get in, make your point, get out. It's harder in a way, because I have to consider the importance of each word. But it's also easier in a way because I don't have to delve too deeply into plot, character, or setting. Plus, I love coming up with a twist or surprise ending.
I bought two books today of short fiction. One is 55 word stories, some of which are really cool. The other is a second volume of short stories, of which I have the first. I'm hoping to get more inspiration and make a collection of stories that may be marketable.
