Who's That Cat Outside?

Hello!  Want to come inside?  It's nice and warm in here, and we have food.

Who are you talking to?

That cat.

What cat?

There's a cat out there.  He looks a little like me, but he's outside.  I think he should come in and get warm, like I did.

That's not another cat.  That's you.

What?  I'm outside?
Wait.  How can I be talking to you right here then?

No, you are still inside.  You're looking at your reflection in the window.

I knew that.
Huh!  Is that a spot on my head?  I need to clean.
