Paris has discovered the train set. He has been setting up the track, which he finds difficult but is very determined to do. Then he sits in the center and tries to drive the train around without it falling off the track . This is also very difficult because the magnets that hold the cars together aren’t very strong and the track is very bumpy. He insists I sit right beside him for assistance in case of a derailment or track breakage. “Ohhh no! ” he says every time it crashes, covering his mouth in distress. I am amazed at his concentration.
