 I admit to listening to this 4 times in a row at work last week. I apologize to my cubemates.
 Tearjerker. Haven't heard Kris yet? In person? My goodness, I don't even respond to much folk music, but this, this... Please, get out there and do so. And Richard Shindell, while you're at it.
 I learn my rap from the movie "Office Space." Also, this is a surprisingly good song to play loud in one's car when feeling overwhelmed.
 I can't believe I like this guy's music. I predict you'll enjoy this song if you're trying hard to pull something off, like get a Ph.D., or start a company, or do just about anything.
 The very isolationist, depressing, freaky lyrics to this once hung in my senior year dorm room.
 I limit the number of times I hear this song because I am afraid that I'll stop finding it so moving.
 Even more so, for sentimental reasons that I will never make light of.
play very loud. cheer up. enjoy.
