You have to work at a relationship.

Unrealistic expectations get in the way.

And Nature says to you: Go stray.

There's more to it than drink smoke strip.

Always On My Mind

Maybe I didn't love you
Quite as often as I could have
Maybe I didn't treat you
Quite as good as I should have

If I made you feel second best
Girl I'm sorry I was blind
You were always on my mind
You were always on my mind

Maybe I didn't hold you
All those lonely, lonely times
And I guess I never told you
I'm so happy that you're mine

Little things I should have said and done
I just never took the time
You were always on my mind
You were always on my mind

Tell me
Tell me that your sweet love hasn't died
And give me
Give me one more chance to keep you satisfied
I'll keep you satisfied

Little things I should have said and done
I just never took the time
You were always on my mind
You were always on my mind

You were always on my mind
You were always on my mind
