Mary was distracted enough that she didn't hear anyone coming until the knock on the door sounded. She finished setting up the dinosaurs for Charlie and told him to make sure to knock them all down before stepping toward the side door that connected them to the main building. She was glad it was close enough that she could still see the main room and the two boys as she carried the baby with her. She peeked through the peep hole and when she recognized James she smiled a bit and opened the door to him and the twins. "Hey there."
