The One Before the One

I heard you're getting engaged Guess I did my job, but I never got paid Oh, I'm one hell of a fixer-upper Being the one before is my bread and butter I put in all the work Took the overtime so you could love her 'Cause it turns out now you're quite a nice guy I was the prototype before your nice life I hate how I helped you To be a better person Not for me, for someone new I'm the girl who lives next to the girl next door I'm the ex who expected a whole lot more I'm the lesson you learned, I'm a leaf that you turned Watched you leave in a carriage while I took the hearse I taught you to love right down to the letter And your mom said you should've treated me better I'm a practice run where you got it all wrong I'm the one The one before the one Must be written on my forehead Been here before, so I'm goddamn sure They'll be perfect by the time they're done with me I should offer a money-back guarantee I'm the girl who lives next to the girl next door I'm the ex who expected a whole lot more I'm the lesson you learned, I'm a leaf that you turned Watched you leave in a carriage while I took the hearse I taught you to love right down to the letter And your mom said you should've treated me better I'm a practice run where you got it all wrong I'm the one The one I won't get the picket fence or the big white dress Or the arguments over dinner sets Was I not enough? Did I fail the test? So you saved it all for someone else There's so many things that you never gave me Like a birthday card or monogamy Or an argument where you let me speak The best of you just wasn't for me I'm the girl who lives next to the girl next door I'm the ex who expected a whole lot more I'm the lesson you learned, I'm a leaf that you turned Watched you leave in a carriage while I took the hearse I taught you to love right down to the letter And your mom said you should've treated me better I'm a practice run where you got it all wrong I'm the one The one before the one
