Over the Left Shoulder

Another thing's always waiting.  Done with this thing?  Make haste, because the next one impatiently glowers over your shoulder.

This might be a recurring theme, here.  What can be said, though?  If it ever gets to the point where nothing productive waits to be done, the grim reaper starts walking up behind you.  As annoying as things get, it's still better to have something to do than nothing.
