To be a short story writer you have to be able to convey yourself as witty and humorous, sad and depressed all in a short amount of time. To get across to your reader the kind of emotion you want to express can be a very daunting task. I do not think that a writer of short stories would be considered lazy at all. I love reading short stories. maybe i am lazy because i'll read a book of short stories over a novel at times. Augesten Burrouhgs and David Sedaris are two short story essayist that i enjoy very much. I think what they do when they write is anything but lazy. The stories may be short but you are getting so much more when you read them. I think it is a small insight into this person's life and it is very intriguing.
