While reading this. I knew something was going to happen, I just didn't know what! And. I thoroughly enjoyed what did happen. The comment, or message, within the piece was apparent. However, the twist at the end was the high point of the read and created a smile for me.
I thought you did a very nice job on this considering the the limits you were working with. The only thing I saw was in the sentence, " He carefully put the saw down and picked up the canvas bag that had been slung over a branch on that tree." I exactly know why, it just didn't flow quite as easily as the rest of the read. It could just be a little long, or maybe the tense isn't quite right. At any rate, it's somewhat a minor thing in an otherwise really enjoyable read that I think could be developed further!
