Look, I've built a time machine   To take us back to when   Your perfect word was "please"   And mine was always "yes"      Grown-ups and "no no" words   They spelled over our heads   We'll go back with all we've learned   And translate what they said      We'll fast forward a year or so   We can't wait here   We have to know   Will we still be each other's or alone?      So on the count of three   A year from now tonight   We'll both turn in bed to see   Who will be sleeping on the other side
