I know this Lyric of the Day will appeal to @VinMcCarthy and his awesome Poem of the Day collection, because you could use this one to teach a class on imagery and its power. It's Janis Joplin's "Me and Bobby McGee".
"Busted flat in Baton Rouge
Waiting for a train
And I's feelin' near as faded as my jeans
Freedom's just another word for nothin' left to lose"
Faded as the jeans... anyone who has been on the road for any extended period of time can surely relate. Sometimes, the spirit of adventure wears on you, regardless of how much fun you're having or how much you're learning. It's tiresome - in the very best way.
