So literal

Tyler and Brody got up from their nap and asked for a snack.  I said, "OK, but mommy's feet are cold and I need my slippers.  Do you think you could go get me my slippers and then I'll get you a snack?  You scratch my back, I'll scratch yours.  How about that?"  And Tyler said, "ok" and then I felt him scratching my back.  My feet are still cold.
