How to tell DS that there's exactly zero chance that his girlfriend can stay here at Thanksgiving?

@NEPatsGirl My room stayed the same for a long time, even when DH and I lived with my parents for a few months before we moved out of state. He thought it was funny that there were still a few remnants of my childhood in there. :))

This all reminds me of one of my favorite SNL sketches - Do It In My Twin Bed. =))
