Our First Brains sweater teeth

Nodding off, you told me the whitest lie.
It's not you, it's the things you do to me.
And ever since I've had an old you in my head that I can barely make out.
And the same punch line when I'm holding you in bed.
We hardly ever make out.
You're cross with me, I'm longing for you.
I floss my sweater teeth to brush off your excuse.
In fact, I've lost them all in all my dreams of you.
How does that make you feel?
How do I rub you the wrong way?
