All the things, that we've been through
You should understand me like I understand you
Now girl I know the difference between right and wrong
I ain't gonna do nothing to break up our happy home
Don't get so excited when I come home a little late at night
'Cause we only act like children when we argue, fuss and fight
the lyrics to "If You Don't Know Me By Now" by Simply Red are pretty mature. written by someone with a bit of life experience.
