you cant do that

I got something to say that might cause you pain
If I catch you talking 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 talking to him
Do I have to tell you one more time, I think it's a sin
I think I' ll let you down (Let you down)
Leave you flat (Gonna let you down and leave you flat)
Because I've told you before, oh
You can't do that
Everybody's green
Cos I'm the one who won your love
But if they'd seen
You're 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'm gonna let you down (Let you down)
And leave you flat (Gonna let you down and leave you flat)
Because I've told you before, oh
You can't do that, 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)
Everybody's green
Cos I'm the one who won your love
But if they'd seen
You're 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'm gonna let you down (Let you down)
And leave you flat (Gonna let you down and leave you flat)
Because I've told you before, oh
You can' t do that
