The Christmas Clause

Claus stepped out of the advent towers feeling like he had missed something. He had gone in there to, to. To what, he couldn’t remember.
“What did you do?” The complex owner asked.
“He said the towers were going to have to come down, because he kept disappearing.”
“So what did you do?”
“Well I brought him in here to talk about turning the reality dampers down a bit...”
“And...”
“Well I turned them all the way up. I think he lost part of his memory of the event. The part where he said the towers had to come down.”
