.bad habit.

You're like my first bad habit
I can't live without it
You're the worst, you're the best
I can't give you up, give you up
And even though you're trouble
I come back for double
I can't say enough is enough
I'm a part of you, you're a part of me
And I know it's wrong but I can't get free
You're like my first bad habit
How am I gonna give you up?
