I'll have to agree with everyone who's praised this 'little' story, I hope it can cope with the weight of all those compliments, but then again it actually really was a 'huge' story when it comes to the images it was able to convey in just a few minutes.
I think Flash Fiction is one of the hardest things to do in this genre, it is really tricky to get it right, since there is so little room to manoeuvre and entice the audience into a setting and plot with just a few words, without the opportunity to give vital information, a lot has to be left to the imagination. I just wanted to mention, I really am amazed and fascinated when I come across one that is so good, since I appreciate the 'craftsmanship'.
If Flash Fiction is done right and the writing is as good as this one, the story comes to life in the listener's mind, and this story seems to be exactly right as far as filling in the gaps and the reader 'constructing' it goes. Quite an accomplishment. WELL DONE. More like this please.
