I had given up the dream

about us lasting for eternity

I had closed that door long ago

but you came waltzing back in

about us lasting for eternity

you waxed some poetic lines

hoping I would reconsider but

I had closed that door long ago

doing whatever I had to do

to move on with my life

until you came waltzing back in

knocking down the walls I built

around my vulnerable heart
