If you were just a habit
Wouldn’t it have taken me too
Twenty-one days to quit
Feeling the way I do about you

And if after twenty-one days
You still linger on my mind
What does the world say
About love of this kind

Because you weren’t just a habit
That I could kick when I wanted
You can’t compare feelings
To a cigarette between my lips
But even if it were that easy
I don’t think I’d choose to kick it
