Lyrics:

I've Heard It Said, What You Don't Know
won't Make You Blue
but Somehow With These Words I Can't Agree
'cause It's Not The Things I Know You Do
that Breaks My Heart, You See
it's The Things That I Don't Know That's Killin' Me

i Don't See You When You Meet Him Secretly
but I Think Your Arms Have Held Him Tenderly
so It's Not The Things I Know You Do
that Breaks My Heart, You See
it's The Things That I Don't Know That's Killin' Me

the Little Things That You Don't Notice
hurts Me So
little Things No One But Me Could Ever Know
i Will Keep Them Hidden So No One Will Ever See
it's The Things That I Don't Know That's Killin' Me

i Don't See You When You Meet Him Secretly
but I Think Your Arms Have Held Him Tenderly
so It's Not The Things I Know You Do
that Breaks My Heart, You See
it's The Things That I Don't Know That's Killin' Me
