When you are listening to Yankee Hotel Fox Trot and you can LITERALLY FEEL SPRING COMING.
You may call it wishful thinking, I'm going to run with a "when one of your senses is diminished, the others are heightened" theory - my depressed ability to function in any social situation is more than compensated by the fact that I can tell when spring is about to arrive, and I know - like KNOW know, that spring is basically here.
All hail the inception of Spring Chicken Syndrome 2009 - you can run, you can hide, but you will get gotten - I can guarantee it.
