(originally by Harold Melvin & The Blue Notes) If you don't know me by now You will never, never never know me All the things that we've been through You should understand me like I understand you Now boy I know the difference, between right and wrong I ain't gonna do nothing to upset our happy home Don't get so excited if I come home a little late at night And we only act like children when we argue, fuss, and fight If you don't know me by now You will never, never, never know me We've all got our own funny moods, I've got mine And boy, you've got yours too Just trust in me like I trust in you As long as we've been together It should be so easy to do Please get yourself together or we might as well say goodbye Cause what good is a love affair when you can't see eye to eye If you don't know me by now You will never, never never know me If you don't know me by now You will never, never never know me
