Worry is a creature that worms its way into the gut; it creeps up the chest, making it difficult to breathe; and then it gnaws at the nerves, fraying them, wearing them out. I had the unfortunate opportunity of reacquainting myself with worry early last Friday morning, when I roused myself slowly from heavy sleep to find 5 missed calls from an unknown number on my phone. A text from the same number revealed that its owner was the mother of a very good friend, and that this friend had just been in a violent car accident.
