The wind behind my back

It's eleven at night and I've just finished a long day at the lab. Now comes the brief ten minute walk south to a warm room, a soothing shower, and some welcome conversation before bed. Tonight the walk home is more brisk than usual because I've got a strong wind at my back, giving me a firm push homeward. I've observed that the winds in this city always seem to blow from the north down to the lake. This peculiar path of the wind coupled with a natural, gentle slope down to the water always makes the walk home a lot easier than the walk to work. Although maybe it might have something to do with my state of mind, too.
