untied

i stand on one end of the board, she drops the rock hard on the other end, and i'm flying through the air, and it's a trip i never planned, and i didn't bring much with me, you wouldn't let me bring much with me, but you're riding now beside me, so where will we land?, you pull the string and i come untied, pull the string and i come untied, you pull the string and i come untied, it's always me coming to your door, with some stuff i found in the trash, and these things i brought you before, well, i guess they didn't match, so now whenever you are down, take me down with you, you pull the string and i come untied, pull the string and i come untied, what's the use if this thing has died?
