Short Story - Resistance

A few months ago I entered into a writing prompt competition on the Writer's Digest website. The challenge was to craft a short story limited to fewer than 750 words using the below prompt:

A man opens his mailbox to find an envelope containing a set of instructions.

Sadly, I did not win the competition, but it was good practice and a short break from my other novels. I've posted the short story in the Writer's Block section of my website. Please check it out here and feel free to comment.
