and then , the last stanza of my song ended , but he was still singing-words i had n't written , lyrics i 'd never heard before , with a new chord added seamlessly to the structure , one i did n't know how to play : you meant more than i could know when i forced you to leave since the day i watched you go i can barely breathe you may wonder whether what we had was true but i break when we 're not together i 'm myself when i 'm with you behind me , the entire baby shower was watching me at the window .
