I couldn't get any air when I was driving to go get a paper this morning. I turned up the nob to the highest setting and still couldn't feel anything. Then I realized what the problem was--all the vents were pointed toward the roof of the car. Sure, I would get some air in a little while, but I was impatient. So I flipped them so they faced me and received a wintery blast of recycled air.
Then I ran over a child.
Life is always strangely analogous.
