Gruesome--I liked it. You have a great way of setting up the story with not much other than conversation. Dave, I believe, may have a bit of the psychopath in him and I think you have a lot to work with if you decide to expand the idea. The only criticism I would offer is to go back through and check grammar. I noticed you used a "they" instead of "the" which wouldn't be noticed by a spell/grammar check. Great Job!!
