This was ridiculous. Just because some rookie teenage doctor - on a totally unnecessary hospital visit - had reckoned Dean's blood pressure was a little up, Sam had insisted on getting this stupid machine so he could monitor himself at home. It was an awkward, annoying and pointless process. He was fine.
Plus, the machine was faulty.
Dean frowned at the display, cleaned it with his shirt-cuff, squinted, and glowered again.
That didn't count.
Obviously, the results were being skewed by the effects of the frustration caused by the last three garbage readings this piece of junk had given him.
