you can't do that lyrics

I've got somethin' to say that might cause you pain
If I catch you talkin' to that boy again
I'm gonna let you down and leave you flat
Because I told you before, oh you can't do that

Well, it's the second time I've caught you talkin' to him
Do I have to tell you one more time I think it's a sin?
I think I?ll let you down and leave you flat
(Let you down)
(Gonna let you down and leave you flat)
Because I told you before, oh you can't do that

Everybody's green ?cause I'm the one who won your love
But if they'd see you talking that way they'd laugh in my face

So please listen to me if you wanna stay mine
I can't help my feelings, I'll go out of my mind
I think I?ll let you down and leave you flat
(Let you down)
(Gonna let you down and leave you flat)
Because I told you before, oh you can't do that

You can't do that, you can't do that
You can't do that, you can't do that
You can't do that

Everybody's green ?cause I'm the one who won your love
But if they'd see you talking that way they'd laugh in my face

So please listen to me if you wanna stay mine
I can't help my feelings, I'll go out of my mind
I think I?ll let you down and leave you flat
(Let you down)
(Gonna let you down and leave you flat)
Because I told you before, oh you can't do that
