I rather liked it; the cyclical structure was kind of chilling, and the whole thing had an air of foreshadowing. It's weel orth the short time it takes to read it. (F!)
It reminds me of Poe's 'A Tell Tale Heart' without the excitement. I was pretty confused about what was going on (either I'm dense or the story was very vague; go for the latter) although the writing was intereting and kept me reading.
