After he had entered a toyshop, he was looking very carefully at all the shelves. He looked up, as if he had seen me, but it was false alarm. His attention was drawn to a little girl that kept talking to her mother about a beautiful dollhouse, on which the mother responded that Santa couldn't afford such an expensive present.
It seemed as if Mister knew her. Nevertheless, he didn't address her and made sure that he was not noticed, just like I did with him.
