I don't know how long I've got on this earth Or what a '57 Chevy's worth I don't know why the world is round Why up is up and down is down I don't know a lot of trivial things Like who invented the washing machine I don't know my way to Timbuktu But I know I love you I know it's hard to teach an old dog new tricks I know havin' money doesn't mean you're rich And I konw a good night's sleep makes you feel brand new And I know I love you I don't know why sometimes the good die young I don't really know anyone who knows the answers to things like that Don't know when Jesus is comin' back I don't know why I've been so blessed Or what the world's gonna hand me next And without you I don't know what I'd do 'Cause I know I love you There's a few little things I know Like old folks drive way too slow And I know with some luck Someday we'll move that slow too And I know I love you And I know fiddles make pretty music Yes they do Just like a good ol' song what we've got rings true And I know I love you And I know I love you
