"I Don't Get It," he says

I see that one of the boys has a few zeroes online for a few assignments. I print out the grade report and tell him he needs to take care of this. He assures me he has the papers and will get them turned in. Well, the next day comes around and the zeroes are still there.

I ask him if he turned in the papers and he said yes.

Then why are there three zeroes online.

Oh I haven't turned those in yet.

So you just lied to me, go to your room.

So after 20 minutes I tell him he can come out and he comes to me and says "Can I ask you something"

Sure.

Why did you say I lied, I didn't lie.

What, you told me you turned in the papers, didn't you?

Yes

And that was a lie, was it not.

Oh, okay, I'm sorry I lied to you.

Sooooooo...I'm thinking surely he knows he lied from the beginning. How does he think he is going to get away with it.

Just another converstion with a teenager. So what kind of consequences can we have here?
